Product Code:SAE USCAR10-2
Title:TEST FOR EVALUATING THE TORQUE-TENSION RELATIONSHIP OF BOTH EXTERNAL AND INTERNAL METRIC THREADED FASTENERS
Issuing Committee:
Scope:This standard provides a test method for determining the torque-tension relationship of both external and internal metric threaded fasteners for the purpose of measuring the frictional characteristics of the threaded fasteners. The results obtained by this test are relevant to the test conditions only and should not be utilized for specific applications.1.1 The test shall consist of a single installation of the sample fastener in a test fixture using a constant speed power tool. The test sample shall be assembled onto an appropriate mating test part (i.e., a nut will be tested by being driven onto a test screw). The test sample shall be driven against a test washer as the bearing surface.
