Scope
This SAE Part Standard covers selected inch screws, hex bolts, and nuts manufactured in accordance with SAE and American Society for Testing and Materials (ASTM) fastener standards. Appendix A covers bolt blanks to manufacture fitted bolts of specific materials. This document covers fastener materials often used in ship systems and equipment but its use may be applied wherever fasteners of the covered materials are used. This document permits the fasteners to be identified and ordered by a part or identifying number (PIN) as defined in this document.
Rationale
Three grades of Ni-Cr-Mo-W alloy (UNS N06686) are now covered. Ni-Cr-Mo-Cb (UNS N06625) is added for high temperature applications. Copper Alloy Brass 260 (UNS C26000) is added to provide a cold heading grade. Bolt blanks are added to reduce machining waste for shipbuilders and repair activities. Continuous threaded cap screws are added for energy absorption applications and also as an option where fit ups vary. SAE J429 and J995 Grade 2 steels are added to primarily support existing applications and are not recommended for new design. A note on galling is added to provide guidance when selecting aluminum, titanium, nickel alloys and austenitic CRES. CRES alloys updated to list those which are listed in referenced product standards. Designators have been added for pigmented overcoats for Zinc/Aluminum coatings.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
