Abigail ★★★★★

These are going to be my go-to for jig work now, the partially threaded design gives me just the grip I need on the fixture plate. The hex socket drive seated perfectly on my driver and the thermal black oxide finish is already holding up well under shop oil.

Emma R. ★★★★★

The black oxide finish looks proper and hasn't flaked off during assembly. These 1/2-20 screws seated cleanly into my jig’s tapped holes, and the hex socket drive held the allen key without stripping.

Isabella ★★★★★

I needed some strong screws for a custom jig I’m building, and these 1/2-20 x 2-1/4" socket cap screws with the hex drive were exactly what I was looking for. The nylon pellet locking feature really impressed me, keeping everything tight during assembly.
