Amendment / Modification

This document contains notes (7040-7043, 7046) that provide additional requirements and specifications for fasteners, modifying or clarifying the base standard MIL-S-1222.

Key modifications and requirements include:

• Material Specification: Fasteners must be ALY-N06686, GR 2, with specific requirements for melting method (EST or vacuum arc remelting), maximum 1% iron content, and 100% longitudinal UT inspection for internal bursts.
• Testing Requirements: Material must pass Charpy V-notch testing (ASTM E23) with specific impact energy minimums. Destructive tests like wedge tension and axial tension testing (ASTM F606-09) are required on full-size fasteners, with SEM inspection for intergranular fracture.
• Manufacturing Method: The only acceptable manufacturing method is fully machined. Vendors must submit a manufacturing plan for approval.
• Material Marking: Fasteners must be marked with "686-2." Self-locking fasteners require specific self-locking inserts (MIL-DTL-18240) and a minimum of six dots for marking.
• Certification and Reporting: Certification reports including material property test results must be supplied for each lot. Representative material samples from tested lots must be provided for metallographic examination.

These notes modify or add to the requirements originally established by MIL-S-1222 and ASTM-B574.

Vendors must adhere to these detailed material, manufacturing, testing, and certification requirements when preparing their proposals or manufacturing the fasteners. A manufacturing plan submission is required for approval prior to manufacturing.
