Joseph M. ★★★★★

I needed some long fasteners for a jig I was building, and these 8-inch alloy steel screws handled the torque perfectly. The black oxide finish adds a nice touch of corrosion resistance too.

Joshua F. ★★★★★

The hex socket drive made installing these in tight spots on my jig much easier than using a wrench. The partially threaded design let me get a solid grip without stripping the threads. Exactly what I needed for a heavy-duty machine repair.

Eva ★★★★★

The black oxide finish on these screws gives them a serious, professional look and seems to handle oil and shop grime without rusting. I’ve been using them to secure a heavy fixture plate, and the partially threaded length grabs perfectly for that setup. Solid purchase for anyone working on tooling.
