scope:

This SAE Part Standard covers selected inch screws, bolts, structural bolts, and nuts manufactured in accordance with ASTM International and SAE fastener standards. Appendix A covers bolt blanks to manufacture fitted bolts of specific materials. This document covers fastener materials 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 identification number (PIN) as defined in this document.

Purpose

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

Part Identification Numbers (PINs)

This document provides PINs that can be used to identify the capscrews, structural bolts and hex nuts covered by this document. The PINs identify material, material strength, coatings and special features, nominal diameter, thread configuration, fastener length, marking requirements, along with the applicable ASTM or SAE fastener specification. The fasteners covered by this document are to be manufactured in accordance with fastener standards issued by the SAE and ASTM with dimensions as identified in ASME and other industry standards cited herein, e.g., coatings.

Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this standard may involve the use of hazardous materials, this standard does not address the hazards that may be involved in such use. It is the responsibility of manufacturers and users to consult with appropriate authorities on the applicable health and environmental regulations regarding the handling, use and disposal of hazardous materials. For fasteners, some of the hazardous materials concerns are the application of the materials in platings (coatings), release of toxic vapors due to heat (for example, welding) and environmental regulations for disposal.
