Sebastian ★★★★★

I needed some short, strong fasteners for a jig I was building and these 1/4-20 socket cap screws fit perfectly. The hex drive seated cleanly and the black oxide finish holds up well to handling.

Amelia U. ★★★★★

The black oxide finish on these screws feels really durable and they fit perfectly into my tooling fixture. I needed a precise 3/16" length for a tight assembly and these were spot on.

David W. ★★★★★

Picked these up for a small jig I'm building, and the hex socket drive makes tightening in tight spots easy. The 3/16" length is exactly right for flush-mounting, and the black oxide finish hasn't shown any wear so far.
