MIL-STD-1312 Fastener Test Methods

← Back to all standards

MIL-STD-1312 is the U.S. military standard defining a series of numbered fastener test methods used to verify the mechanical and durability properties of threaded and related fasteners. To match this to your program, talk with our team.

What MIL-STD-1312 Covers

It covers a family of numbered fastener tests, including tensile, and fatigue and other durability methods, referenced by method number for defense and aerospace fastener qualification.

How the Test Is Run

Fasteners are tested by the applicable numbered method, including tensile and proof loading in suitable fixtures or cyclic loading for fatigue methods, and results are checked against the requirement.

Why It Matters

Standardized fastener verification supports defense and aerospace reliability; high-force grips, threaded adapters sized to the fastener, and fatigue-capable loading where required are essential.
