SAE J174Torque-Tension Test Procedure for Steel Threaded Fasteners, Inch Series
This test procedure is intended to provide a quality control method for checking torque-tension characteristics of non-prevailing torque type threaded steel fasteners 1/4 through 1 in nomial diameters. Realistically, torque-tension relationships for specific individual fastener assembly joints will vary due to the different joint parameters. Tests using actual joint components will be required to determine accurate torque-tension values for those conditions. For the metric version, see SAE J174M.
Before conducting SAE J174, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
