Standard Test Methods for Determining the Mechanical Properties of Externally and Internally Threaded Fasteners, Washers, Direct Tension Indicators, and Rivets

Standard Test Methods for Determining the Mechanical Properties of Externally and Internally Threaded Fasteners, Washers, Direct Tension Indicators, and Rivets

ABSTRACT
These test methods establishes the standard procedures for conducting tests to determine the mechanical properties of externally and internally threaded fasteners, washers and direct tension indicators, and rivets. For externally threaded fasteners, the mechanical tests describe the procedures for determining the following properties: product hardness; proof load by length measurement (Method 1), yield strength (Method 2), yield strength of austenitic stainless steel and nonferrous materials (Method 2A), and uniform hardness (Method 3); axial tension of full size products such as fasteners and studs; wedge tension of full size products such as fasteners and studs; tension of machined test specimens including yield point (by drop of the beam or halt of the pointer, autographic diagram, and total extension under load methods), yield strength (by offset, and extension under load methods), tensile strength, elongation, and reduction of area; and total extension at fracture. As for internally threaded fasteners including nonheat- and heat-treated nuts, tests are provided for the determination of product hardness, proof load, and cone proof load. Test for determining the surface and core hardnesses are, conversely, described for direct tension indicators, and through-hardened, carburized, stainless steel, and nonferrous washers. And finally, product hardness testing is described for rivets. The test method for determining embrittlement of metallic coated externally threaded fasteners is detailed as well.
SCOPE
1.1 These test methods cover establishment of procedures for conducting tests to determine the mechanical properties of externally and internally threaded fasteners, washers, direct tension indicators, and rivets.  
1.2 Property requirements and the applicable tests for their determination are specified in individual product standards. In those instances where the testing requirements are unique or at variance with these standard procedures, the product standard shall specify the controlling testing requirements. In the absence of any specified test requirement(s), these test methods shall apply.

ASTM F2328-17(2022)(Test Method)
Standard Test Method for Determining Decarburization and Carburization in Hardened and Tempered Threaded Steel Bolts, Screws, Studs, and Nuts

SIGNIFICANCE AND USE
4.1 Decarburization and carburization are two surface conditions created, either intentionally or unintentionally, as with a pre-existing condition created during the rod rolling process, the rod/wire annealing process, or while heat treating threaded steel products. Too much of either will adversely affect the safety and performance of the threaded product. Therefore, limits have been established for three different product groups: the harder and greater the tensile strength of the product, the more susceptible to failure the product becomes if these limits are exceeded.  
4.2 When testing to a particular product specification that lists the dimensions and microindentation data to be used, that data shall take precedence over the tables in this test method.  
4.3 There are only two viable methods available to detect these deficiencies, either by the visual method or the microindentation method. Both methods are used for routine inspections when evaluations are conducted at a single location on the product sample.  
4.3.1 Because an evaluation at a specific location may not be representative of the whole part, the referee method employs the microindentation method taken as an average of evaluations conducted on four adjacent threads. This procedure significantly reduces the random test variables when compared to testing on a single thread.  
4.4 Specifying this test method does not specify or imply that testing shall be for either decarburization or carburization alone or for both conditions. When either test method is performed, both conditions will be apparent and shall be reported. For example, if an order is placed to test for decarburization and none is found, but the presence of carburization is detected, it shall be reported on the test report that carburization was found.
SCOPE
1.1 This test method covers procedures for measuring, classifying, and determining the presence of decarburization and carburization in the threaded section of hardened and tempered inch series steel bolts, screws, studs, nuts, and similar parts which have been heated to facilitate fabrication or to modify their mechanical properties. This test method is not intended to address products which are intentionally carburized to achieve specific results.  
1.2 Two routine methods are described for measuring the limits of and determining the presence of decarburization or carburization—the optical method and the microindentation method 1. Either method is appropriate for routine examinations. The microindentation method 2 shall be considered the referee method.  
1.3 For the purpose of these tests, there are four classes of hardened and tempered steel products for which specific measurements must be made with respect to their physical properties.  
1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Accelerated Corrosion Testing for Mechanical Fasteners

ABSTRACT
This guide covers test procedures for performing accelerated tests to evaluate relative corrosion resistance of various coatings applied to mechanical fasteners. Corrosion mechanisms such as general and crevice corrosion may be evaluated with this method. Test duration may be selected to achieve any desired level of corrosion exposure and provides a frame of reference to determine relative coating resistance to corrosion. Fasteners tightened to a desired tension and subjected to this test procedure may be evaluated to simulate a variety of service conditions. Without large amounts of accumulated field results, it is difficult to relate test duration or the number of test cycles to actual service life for a given application.

ASTM F3359/F3359M-21(Test Method)
Standard Test Method for Determining Bending Yield Moment of Staples

SIGNIFICANCE AND USE
5.1 Staples are mechanical fasteners used in wood structures. Engineering design procedures used to determine the capacities of laterally-loaded staple connections use a yield theory to establish nominal resistance (Note 2). In order to develop nominal resistance for laterally-loaded stapled connections, the bending yield moment must be known.
Note 2: When used as a structural fastener in shear walls and diaphragms, staples are installed with the crown parallel to the long dimension of the framing member. The orientation of the staples for this bending yield moment test represents the bending yield moment applicable for this intended use).
SCOPE
1.1 This test method covers procedures for determining the bending yield moment of staples when subjected to static loading. Although intended for flat crown staples identified in Specification F1667/F1667M, this procedure is also applicable for staples with round wire. These staples are used in engineered wood building connection applications for which required connection capacities are specified by the designer.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
Note 1: This test method is applicable in either inch-pounds F3359 or SI Units [F3359M]. Values stated in SI are a mathematical conversion and are shown in brackets [ ].  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.2 In case of conflict, the requirements of the individual product specification shall prevail over those of this specification.  
1.3 Fasteners are a wide-ranging classification that includes screws, bolts, nuts, washers, stud bolts, rivets, powder-actuated studs, staples, tacks, and pins. Bolting, which is composed of bolting materials, such as rods, bars, flats, and forgings, which are subsequently manufactured into bolting components, are a special sub-group of fasteners. Bolting materials and components have designated compositions and specific properties intended for applications in aggressive service where commercial generic fasteners may not be suitable or have insufficient fitness for purpose under certain conditions. These conditions include cryogenic or high temperature service, or excessive vibration, impact, or shock. To further address any other special service conditions where bolting is intended for use, additional requirements may be specified by mutual agreement between the purchaser and supplier.  
1.4 Supplementary requirements are provided for use at the option of the purchaser. The supplementary requirements only apply when specified individually by the purchaser in the purchase order or contract.  
1.5 This specification is expressed in both inch-pound units and in SI units. Unless the purchase order or contract specifies the applicable “M” specification designation (SI units) the inch-pound units shall apply. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; there...

ASTM D8509/D8509M-23(Guide)
Standard Guide for Test Method Selection and Test Specimen Design for Bolted Joint Related Properties

SCOPE
1.1 This guide covers the test method selection and associated test specimen design to produce test data to be used for typical bolted joint analyses. These test methods are limited to use with multi-directional polymer matrix composite laminates reinforced by high-modulus fibers. This standard is intended to be used by persons requesting these test types.  
1.2 Test requestors designing these specimens need to be familiar with the referenced Test Method and Practice standards, CMH-17 Volume 3 Chapter 11, and the stress analysis methods that will use the resulting design data.  
1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3.1 Within the text the inch-pound units are shown in brackets.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5649-15(2023)(Test Method)
Standard Test Method for Torque Strength of Adhesives Used on Threaded Fasteners

SIGNIFICANCE AND USE
5.1 This test method provides reasonably accurate information with regard to the determination of the securing or locking effect of adhesives used in threaded fasteners. This test method may also be used to determine the degree of cure and the effect of environment on torque strength.  
5.2 The accuracy of the test results depends to a large degree on the thread clearance of the test fasteners and the inclusion of air bubbles in the bond line. Data generated by this test method should be safety-factored accordingly if used as quality assurance acceptance or rejection.
SCOPE
1.1 This test method is used to make comparative assessments of the securing or locking effect of adhesives used in threaded assemblies.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Alloy-Steel and Stainless Steel Bolting for High Temperature or High Pressure Service and Other Special Purpose Applications

ABSTRACT
This specification covers alloy steel and stainless steel bolting material for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications. Ferritic steels shall be properly heat treated as best suits the high temperature characteristics of each grade. Immediately after rolling or forging, the bolting material shall be allowed to cool to a temperature below the cooling transformation range. The chemical composition requirements for each alloy are presented in details. The steel shall not contain an unspecified element for ordered grade to the extent that the steel conforms to the requirements of another grade for which that element is a specified element. The tensile property and hardness property requirements are discussed, the tensile property requirement is highlighted by a full size fasteners, wedge tensile testing.
SCOPE
1.1 This specification2 covers alloy and stainless steel bolting materials and bolting components for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications. See Specification A962/A962M for the definition of bolting. Bars and wire shall be hot-wrought and may be further processed by centerless grinding or by cold drawing. Austenitic stainless steel may be carbide solution treated or carbide solution treated and strain-hardened. When strain hardened austenitic stainless steel is ordered, the purchaser should take special care to ensure that Appendix X1 is thoroughly understood.  
1.2 Several grades are covered, including ferritic steels and austenitic stainless steels designated B5, B8, and so forth. Selection will depend upon design, service conditions, mechanical properties, and high temperature characteristics.  
1.3 The following referenced general requirements are indispensable for application of this specification: Specification A962/A962M.
Note 1: The committee formulating this specification has included several steel types that have been rather extensively used for the present purpose. Other compositions will be considered for inclusion by the committee from time to time as the need becomes apparent.
Note 2: For grades of alloy-steel bolting suitable for use at the lower range of high temperature applications, reference should be made to Specification A354.
Note 3: For grades of alloy-steel bolting suitable for use in low temperature applications, reference should be made to Specification A320/A320M.  
1.4 Nuts for use with bolting are covered in Section 13.  
1.5 Supplementary Requirements are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified in the purchase order or contract.  
1.6 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.  
1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
