Andrew X. ★★★★★

Put these in a jig fixture I was building, and the black oxide finish held up way better than plain steel screws I've used before. The hex drive seated perfectly in my allen key with no stripping.

Carter ★★★★★

I needed a batch of 5/16-24 screws for a new jig I was building, and these fit perfectly with zero wobble. The hex socket drive made installation quick with just a standard hex key.

Benjamin ★★★★★

The thermal black oxide finish on these cap screws looks sharp and should hold up well in our tooling fixtures. I picked up a pack of 100 for 5/16-24 hardware and the hex socket drive fits snugly without stripping. Solid choice for precision assemblies.
