Nicholas D. ★★★★★

I needed a bulk supply for a few repair jobs and these 1/4-20 hex head cap screws came through perfectly. The fully threaded design grabbed securely in my tap, and the hex head drove true without stripping. Solid value for a project box staple.

Harper V. ★★★★★

The yellow zinc coating actually holds up well against shop grime, and the fully threaded shafts grab cleanly every time. For a bulk box of 400, these hex heads seem to be a solid deal for general assembly work.

Victoria ★★★★★

Grabbed these for a small jig I was building, and the hex heads seat nicely with a socket. The yellow zinc finish has held up well against the garage humidity so far.
