Abigail ★★★★★

The threads are cut clean and square, so they seat flush without any wobble when torqued down on my jig fixture. The black oxide finish gives them a nice, even look and hasn't chipped after a week of assembly and disassembly.

Amelia D. ★★★★★

I’ve been using these for a few custom tooling jigs, and the black oxide finish is holding up well against shop grime. The hex drive bites firmly without stripping, even at higher torque settings. Glad I bought a pack for these precision jobs.

Sophia ★★★★★

I needed replacements for a tooling jig, and these 1/2-20 socket cap screws fit perfectly with no slop. The black oxide finish gives them a nice, even look and seems like it'll resist grime better than the plain steel ones I had before.
