J2485_201212 - Fastener Part Standard - Machine Screw Nuts (Metric and Inch)

Document Number: J2485_201212
Revision Number:
Fastener Part Standard - Machine Screw Nuts (Metric and Inch)
This SAE Part Standard covers selected machine screw nuts manufactured in accordance with American Society for Mechanical Engineers (ASME) dimensional standards. This document covers material most often used in ship systems and equipment but its use may be applied wherever nuts of the covered materials are used. This document permits the nuts 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 in providing requirements and PINs for the most commonly used machine screw nuts. A 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. 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 officials on the applicable health and environmental regulations regarding the handling, use and disposal of hazardous materials. For nuts, 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.
