Chloe Z. ★★★★★

Finally, some hex head cap screws that actually fit the grade 5 spec without being soft—these threaded cleanly into my equipment mounts. The yellow zinc finish looks solid, and the 200-count pack is perfect for stocking up.

Owen X. ★★★★★

I’ve been using these for a few weeks on a heavy-duty jig, and the hex head grips really well with a socket driver. The yellow zinc finish seems to hold up fine so far, no issues with rust.

Eli Y. ★★★★★

The hex heads fit my socket wrench perfectly, which made installing these on a jig a breeze. The yellow zinc coating looks solid and should hold up well in my shop. Pack of 200 is more than enough for multiple projects.
