Title:Fastener Part Standard - Machine Screw Nuts (Metric and Inch)
Issuing Committee:Ship Systems - Fasteners Committee
Scope:This SAE Part Standard covers selected machine screw nuts manufactured in accordance with American Society for Mechanical Engineers dimensional standards. This document 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 document permits the fasteners to be identified and ordered by a part or identifying number (PIN) as defined in this document.PurposeThe purpose of this document is to assist the designer and other personnel in providing requirements and part identifying numbers for the most commonly used machine screw nuts. A part or identification number 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.Machine Screw Nut Part NumbersThis document provides part or identifying numbers that can be used to identify machine screw nuts covered by this document. The part identification number (PIN) identifies the thread form, configuration (shape), nominal diameter, special features (plating and coatings), and fastener material.
