Customer Reviews (4.8 / 5 · 5 reviews)

Lily ★★★★★

The nylon patch on these screws holds tight under vibration, which saved me from having to add threadlocker on my jig setup. They're fully threaded and the black oxide finish looks clean on my tooling. Exactly what I needed for precision assemblies.

Eva ★★★★★

I needed a few hundred of these for a fixture build and the hex socket drive made installation quick with a ball-end Allen key. The nylon patch is a nice touch for vibration resistance. These came well-packed and look exactly as described.

Richard ★★★★★

The black oxide finish on these screws looks tough and hasn't chipped during my jig assembly work, and the hex socket drive makes them easy to install with a standard Allen wrench. They thread smoothly into pre-tapped holes without any binding, which saved me time on a recent tooling project.
