Standard Test Methods for Determining the Mechanical Properties of Externally and Internally Threaded Fasteners, Washers, and Rivets [Metric]

SCOPE
1.1 These test methods establish procedures for conducting tests to determine the mechanical properties of metric externally and internally threaded fasteners, washers, 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 shall specify the controlling testing requirements.
1.3 These test methods describe mechanical tests for determining the following properties:Tests Section For Externally Threaded Fasteners: 3 Product Hardness3.1Proof Load3.2.1 Method 1, Length Measurement3.2.3Method 2, Yield Strength3.2.4Method 3, Uniform Hardness3.2.5Axial Tension Testing of Full Size Products  3.4 Wedge Tension Testing of Full Size Products  3.5 Tension Testing of Machined Test Specimens  3.6 Total Extension at Fracture Test3.7 For Internally Threaded Fasteners: 4 Product Hardness 4.1 Proof Load4.2 Cone Proof Load Test 4.3For Washers and Direct Tension Indicators:5 General Requirements5.1 Through Hardened Washers5.2 Carburized Washers5.3 For Rivets: 6 Product Hardness6.1 Test for Embrittlement of Metallic Coated Externally Threaded Fasteners 7 Test Method for Measuring Compression Loads (All Finishes) on Direct Tension Indicators Covered by Test Method F 959MAnnex A1
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 all of the users of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—These test methods are the metric companion of Test Methods F 606.
