Ship Systems and Equipment - Threaded Fasteners - Inspection, Test, and Installation Guidance

2019-02-13
WIP
J2270

This SAE Standard covers both quality assurance and installation requirements for fasteners.

This document establishes engineering criteria and guidance for quality assurance requirements (including Test and Inspection) for procurement of threaded fasteners where such criteria and guidance is not otherwise provided by existing fastener standards or specifications. The document also provides requirements and test procedures for self-locking fasteners including those manufactured by the installing activity.

This document also provides requirements for the selection and use of fastener lubricants, additional corrosion protection treatments, fastener tightening procedures, and the use of thread-locking compounds.
