Customer Reviews (4.4 / 5 · 5 reviews)

Miles ★★★★★

Ordered a thousand of these for jig building and every single one has clean threads and a uniform drive pocket—no duds in the batch. The button head profile sits nice and low, which is exactly what I needed for tight clearance assemblies.

Ruby F. ★★★★★

The hex drive on these button head screws fits my T-handle wrench perfectly without any wobble, and the 18/8 stainless finish looks clean on my jig fixture. I’ve used about 40 so far and all threaded smoothly into tapped holes.

Richard ★★★★★

Finally found a bulk pack of 5/16-18 socket cap screws that actually hold up in our jigs without rusting. The hex drive makes installation a breeze with no stripped heads, and 1000 pieces should last us a good while.
