Customer Reviews (4.6 / 5 · 5 reviews)

Ruby Y. ★★★★★

I needed a batch of high-strength bolts for a large press fixture, and these black oxide screws matched the alloy steel spec perfectly. The hex socket drive made it easy to torque them down precisely in tight spots, and the partially threaded design held the load just as I needed.

Claire T. ★★★★★

Installing these into my jig frame, the partially threaded design made alignment far easier than fully threaded bolts. The black oxide finish looks professional and seems tough. Exactly what I needed for tooling at the shop.

Christopher C. ★★★★★

I needed these for a jig I was building, and the 3-1/2" length was exactly what I required. The hex socket drive works perfectly with my standard Allen keys, and the threads engaged smoothly into the tapped holes.
