This SAE Recommended Practice defines, illustrates, and specifies allowable limits for various types of surface discontinuities that may occur during the manufacture and processing of bolts, screws, and studs in sizes through 24 mm or 1 in diameter inclusive with lengths to 150 mm or 6 in inclusive, having specified minimum tensile strengths of 900 MPa or 120 000 psi and greater, which are primarily intended for use in automotive assemblies. The basic recommended practice does not include inspection sampling requirements. It is intended that the purchaser shall specify, in the original inquiry and purchase order, the inspection sampling requirements which the producer must satisfy to demonstrate the acceptability of bolts and screws with respect to surface discontinuities.
The SAE Fasteners Committee has reviewed and compared both SAE J1061 and ASTM F788/F788M. It has been determined that there is enough similarity between these two documents that ASTM F788/F788M covers the requirements as intended according to SAE J1061. SAE J1061 is canceled and superseded by ASTM F788/F788M.
