SAE J174MTorque-Tension Test Procedure for Steel Threaded Fasteners - Metric 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 6 through 24 mm nominal 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 inch series version, see SAE J174.
Before conducting SAE J174M, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
