Customer Reviews (4.6 / 5 · 5 reviews)

Ruby U. ★★★★★

The black oxide finish handles my oily workshop environment without a hint of rust, and the hex drive bites cleanly every time—no stripped heads on these. Used a dozen in a jig build and all 100 came out perfectly threaded.

Stella ★★★★★

I needed a handful of these for a small tooling jig, and the hex socket drive made installation much easier than slotted screws. The black oxide finish is holding up well even after a few adjustment cycles.

Thomas W. ★★★★★

The hex socket drive made installation much easier than using a standard slotted head in tight spaces. I used a dozen of these for a small jig build and every one seated cleanly without stripping. Great fit and finish for the price.
