Why surplus hardware from SpecBolt

Same specs, same certifications, same thread pitch. The only difference is the price tag and the fact that someone else's inventory loss is your gain.

Full Certification Trail

Surplus Pricing, New Quality

Certified surplus hardware meets the same AN, MS, and NAS specifications as new. Your annual condition inspection doesn't care where you bought the bolt, it cares that it's the right bolt.
