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.

Included herein are general, dimensional, and performance specifications for those types, styles, and sizes of stamped nuts of one pitch thread design recognized as SAE standard. These nuts are intended for general use where the engagement of a single thread on the mating screw or unthreaded stud is considered adequate for the application. For the metric equivalent of this document, see SAE J1053M.

The Dryseal American Standard Taper Pipe Thread, the Dryseal American Fuel Internal Straight Pipe Thread and the Dryseal American Intermediate Internal Straight Pipe Thread covered by this standard conform with the American Standard ASA-B2.2. The Dryseal SAE-Short Taper Pipe Thread in this standard conforms with the Dryseal American Standard Taper Pipe Thread except for the length of thread, which is shortened for increased clearance and economy of material. The significant feature of the Dryseal thread is controlled truncation at the crest and root to assure metal to metal contact coincident with or prior to flank contact. Contact at the crest and root prevents spiral leakage and insures pressure-tight joints without the use of a lubricant or sealer. Lubricants, if not functionally objectionable, may be used to minimize the possibility of galling in assembly.

This SAE Recommended Practice covers methods for measuring, classifying, and specifying decarburization in the threaded section of hardened and tempered steel bolts, screws, studs, and similar parts. It is not intended to cover products which are specifically carburized to achieve special properties.
