Customer Reviews (4.8 / 5 · 5 reviews)

Sofia ★★★★★

The black oxide finish is uniform and the threads are clean with zero burrs across all 100 pieces. Torqued them down on a fixture plate at 90 ft-lbs and not a single one stripped or showed any sign of yielding.

Joshua ★★★★★

Got these for a jig I’ve been putting together, and the fully threaded length really helps with clamping thicker parts. The hex socket drive makes tightening them easy without stripping, even in tight spots.

Brian O. ★★★★★

Fit perfectly on my milling machine fixture, and the black oxide finish looks clean and professional. The hex socket drive made tightening them down quick with a standard Allen key.
