- 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.
- Content
- Clarify Section 1.1 regarding sampling plans. First sentence appeared contradictory to what is included in Section 5. Removed second sentence as it was not necessary and didn’t add anything to this particular recommended practice.Section 4.9 modified to effectively increase the allowable torque for inspection of nicks and gouges on larger fasteners. These fasteners can be more susceptible to thread damage during bulk handling processes, but are also typically tightened to greater torque specifications with tightening tools offering greater torque capability.Section 5.1 modified to clarify inspection sampling for nicks and gouges.
