Matthew ★★★★★

The thermal black oxide finish looks great and feels durable, exactly what I needed for a jig project. These hex socket screws fit perfectly and the 175-pack will last me a while.

Carter C. ★★★★★

Finally, a socket cap screw that doesn’t strip when I’m torquing down a fixture with an Allen key—the hex socket drive engages cleanly every time. The thermal black oxide coating has held up through a few greasy shop days without a hint of rust. These are going straight into my jig builds from now o

Ella ★★★★★

The black oxide finish on these screws is exactly what I look for in tooling work, and the hex socket drive seated perfectly with my Allen keys. All 175 of them came out of the box with clean threads and no burrs. I've already used a dozen on a jig and they haven't budged.
