scope:

This specification defines the requirements for alloy steel externally threaded fasteners procured under part numbers listed on drawings which refer to this specification. Typically these fasteners are used for tension, shear, and tension-fatigue applications where 180 KSI Ftu and 108 KSI Fsu is desired with a service temperature capability to 450° F. Receiving contractors may reject any manufacturing lot whit does not conform.

The specification includes mechanical property requirements for two classes of fasteners as follows:

Type I - Tension head (hex, double hex, 12 spline, etc. without an internal or recess drive) and studs.

Type II - 100° full flush head and internal wrenching (pan, fillister, brazier, etc.) head configuration.

Workmanship of fasteners shall conform with aircraft fastener manufacturing processes.

Recommendations for improvements or corrections to this specification should be directed to an NASC representative of a using company or to the Executive Secretary of the National Aerospace Standard Committee.

Specifications listed herein, of the issue in effect on date of inquiry, are a part of this specification to extent indicated. In the case of conflict, the requirements herein shall take precedence.

Unless otherwise specified, part inventory manufactured to MIL-B-8831 or previous revisions of the applicable drawing or specification may be procured and used until stock is depleted.
