Customer Reviews (4.2 / 5 · 5 reviews)

Christopher ★★★★★

Needed these for a jig I was building and the fit in the tapped holes was spot on — no binding or slop. The hex socket drive made installation quick with just an Allen key. Fifty of them should last me through several more projects.

George ★★★★★

I needed precise threads for a jig I was building, and these thermal black oxide screws threaded in smoothly with no binding. The hex socket drive seated perfectly on my driver.

Abigail Q. ★★★★☆

The black oxide finish held up nicely during my tooling setup, no chips or wear after threading into hardened steel. These bolts seated smoothly with a hex key, though I wish the package included a few extras for the price. Solid fasteners for jigs and precision work.
