Customer Reviews (4.6 / 5 · 5 reviews)

Lucy ★★★★★

The black oxide coating on these screws matched perfectly with my dark machinery frame, no glare. I used a dozen for a jig build and the hex socket drive gripped firmly without stripping. Solid feel for the price.

Brian U. ★★★★★

The thermal black oxide finish held up perfectly during assembly, no chips or flaking even when I torqued them into a steel fixture. Thread engagement felt smooth all the way down, and the partially threaded design gave just the right grip for my tooling setup.

Henry ★★★★★

Needed a specific length for a jig I was building and these 1/4-20 partially threaded screws fit the bill perfectly. The hex socket drive made installation quick and clean.
