Customer Reviews (4.8 / 5 · 5 reviews)

George G. ★★★★★

The black oxide finish is holding up well in my machining fixture so far, no chips or rust after a week of use. Threads cut clean and easy without any binding during installation.

Sebastian ★★★★★

Needed long cap screws for a custom tooling setup and these threads engaged perfectly, no binding at all. The black oxide coating gives them a nice, uniform finish that should resist rust well in the shop. Really solid feel in the hand, exactly what I expected from USA-made alloy steel.

Olivia J. ★★★★★

Installed these in a jig fixture at work and the black oxide finish held up well against minor coolant splash. The hex socket drive gave a solid grip without stripping, and the full 4-1/2" length was exactly what I needed for that deep assembly.
