BOLTS AND SCREWS - EXTERNAL WRENCHING UNJ THREAD, INCH SERIES - DESIGN PARAMETERS FOR
- Aerospace Standard
Published December 04, 1992 by SAE International in United States
The scope of this document is to fully define the following dimensional requirements for hexagon and double hexagon head bolts having a minimum tensile strength ranging up to 220 ksi.
Head dimensions (see 3.1)
Shank dimensions (see 3.2)
Geometric control (see 3.3)
Surface texture (see 3.4)
For design calculations the MIL-S-8879 coarse threads, UNJC, shall be used for .164 size and smaller and fine threads, UNJF, for larger sizes.
For particulars of thread runout and lead threads, see AS3062.

E-25 General Standards for Aerospace and Propulsion Systems
The SAE E-25 General Standards for Aerospace & Propulsion Systems committee addresses aerospace propulsion systems and components. These systems and components include bolts, screws, nuts, washers, studs, rivets, pins, covers, O-rings, brackets, plugs and associated procurement requirements, as well as solid film lubricants and design specifications for screw threads and fastener assembly requirements.
* 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.
