This SAE Part Standard covers selected inch dimensioned tapping screws and metallic drive screws manufactured in accordance with American Society for Mechanical Engineers dimensional standards. This SAE standard covers material most often used in ship systems and equipment but its use may be applied wherever fasteners of the covered materials are used. This standard permits the fasteners to be identified and ordered by a part or identifying number (PIN) as defined in this standard.

Purpose

The purpose of this document is to assist the designer and other personnel in providing requirements and PINs for the most commonly used tapping and metallic drive screws. A PIN is normally required for all military applications and provides a useful means of communicating screw requirements to suppliers and manufacturers in a very succinct manner.

Tapping Screws and Metallic Drive Screw Part Numbers

This document provides PINs that can be used to identify the screws covered by this standard. The parts covered by this standard are manufactured in accordance with materials and processes identified in applicable standards issued by ASME, ASTM and SAE. The PIN identifies the type thread and point, nominal diameter, head style and drive, nominal length, fastener material, and finish (coating).
