Torque-Tension Tightening for Metric Series Fasteners

2022-03-29

CURRENT

J1701M_202203

This SAE Information Report is provided as an advisory guide. Individual application discretion is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. The document covers a number of the variables in the torque-tension relationship: friction, materials, temperature, humidity, fastener and mating part finishes, surfaces, and the kind of tightening tools or equipment used. Also described in this document is the torque management required to achieve satisfactory fastened joint tightening. This guide is limited in application to clearance fit threads, such as the common 6g/6H class of fit. Other thread types including interference fit, mechanical locking, prevailing torque, or forms other than ISO-metric may apply to some aspects of this standard but are not specifically covered.

HISTORICAL

J174_199805

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 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 metric version, see SAE J174M.
