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.
1.3 These test methods describe mechanical tests for determining the following properties:
