Customer Reviews (4.6 / 5 · 5 reviews)

Matthew V. ★★★★★

Machined a set of fixture plates over the weekend and these 12.9s torqued down clean without a single stripped head. The black oxide finish looks sharp and held up well against the cutting oil. Packaging was solid too, no rattling or damaged threads.

Madison ★★★★★

Pulled these out of the package for a jig I'm building—the black oxide finish feels smooth and even, and the partial threading grabbed just right in my tapped holes. No stripping or wobble when torqued down.

Julian ★★★★★

Needed some high-strength bolts for a custom tooling setup and these fit the bill perfectly. The partially threaded design made alignment much easier in a tight spot, and the black oxide finish survived a few drops without scratching.
