- Content
- This SAE Recommended Practice defines, illustrates, and specifies allowable limits for various types of surface discontinuities that may occur or become apparent during the manufacture and processing of bolts, screws, and studs which are primarily intended for use in automotive assemblies subjected to severe dynamic stresses and necessitating use of high strength fasteners having appropriate fatigue-resistant properties.
- Content
- The SAE Fasteners Committee has reviewed and compared both SAE J123 and ASTM F788/F788M including Supplementary Requirement S1. It has been determined that there is enough similarity between these two documents that ASTM F788/F788M (including S1 requirements) covers the requirements for automotive assemblies as intended according to SAE J123.Please note that Supplementary Requirement S1 is intended for use only on fasteners subjected to severe dynamic stresses. When this requirement is specified, the fastener manufacturer must significantly increase production controls including machine set-up, blank diameters, die lubrication, in-process inspection requirements, and reduced production rate.
