ASTM F606/F606M — Mechanical Testing of Threaded Fasteners, Washers, DTIs, and Rivets

← Back to all standards

ASTM F606 is the test-methods standard for determining the mechanical properties of externally and internally threaded fasteners, washers, direct-tension indicators, and rivets. To match this to your program, talk with our team.

What ASTM F606 Covers

It defines proof load, tensile strength, wedge tensile, hardness, and related tests for bolts, screws, studs, and nuts, the core mechanical checks for fastener acceptance.

How the Test Is Run

Fasteners are loaded in tension, proof loaded, or wedge tested using suitable fixtures, and the measured strength or proof performance is compared against the product specification.

Why It Matters

Verified fastener strength underpins bolted-joint safety; high-force grips, wedge fixtures, and threaded-adapter tooling sized to the fastener are essential.
