Fasteners Part Standard--Cap Screws, Hex Bolts, and Hex Nuts (Inch Dimensioned)
This SAE Standard provides part numbers for the identification of fasteners for ship systems and equipment. This document lists some of the more common industry standards that have associated part numbering systems. In addition, this document provides part numbers for screws and nuts to American Society for Testing and Materials (ASTM) fastener standards covering materials most often used in ship systems and equipment.
The purpose of this document is to assist the designer and other personnel in providing standard part numbers for the most commonly used fasteners for ship systems and equipment. A part identification number (PIN) is normally required for all military applications and provides a useful means of communicating fastener requirements to suppliers and manufacturers in a very succinct manner.
