This SAE Part Standard covers selected inch dimensioned set 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 document.

Purpose

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

Set Screw PINs

This document provides PINs that can be used to identify set screws covered by this standard. The fasteners covered by this standard are manufactured in general accordance with materials and processes identified in standards issued by ASTM. The PIN identifies the thread form, type of head, type of drive, nominal diameter, special features (plating, locking elements), nominal length and fastener material.

Procurement Specification Safety - Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.

Certain elements and their compounds are considered hazardous or toxic materials by the United States (US) Environmental Protection Agency (EPA) and Occupational Safety and Health Agency (OSHA.)
