Ruby Q. ★★★★★

The flat head design sits flush in my jig plate, and the black oxide finish hasn't shown any wear after a few dozen test runs. Exactly the right fit for those 5/16-18 tapped holes.

Alexander ★★★★★

I was pleasantly surprised by how precisely these screws fit into my jig fixture—the hex socket drive made installation a breeze. The 100-count pack is perfect for stocking up on a common size for various small projects.

Hannah T. ★★★★★

The black oxide finish on these screws is holding up perfectly in my tooling setup. They fit securely with no wobble, and the flat head sits flush every time.
