Emily Q. ★★★★★

I needed a bunch of Grade 8 fasteners for a trailer build, and these fully threaded screws with the hex head are super easy to drive with a socket. The yellow zinc coating looks consistent across all 3000 pieces, no duds in the box.

Avery Q. ★★★★★

These 3000 hex cap screws came exactly as described, the Grade 8 zinc coating looks tough enough to handle heavy assembly work. I like that they’re fully threaded and the 5/8" length works perfectly for securing brackets.

Leo ★★★★★

I needed a bulk order for a shop rebuild and these Grade 8 screws are tough enough for heavy machinery; the hex heads grab the socket perfectly without stripping.
