Customer Reviews (4.6 / 5 · 5 reviews)

Sebastian B. ★★★★★

The yellow zinc coating is uniform and bright, and every single thread on these cap screws is clean and sharp. I’ve used about 40 of them so far for a machine base and haven’t had a single one bind up or strip on install.

Nicholas ★★★★★

The yellow zinc finish is spot-on and the threads cut clean without any binding when I ran them into my equipment frame. Each pack of 110 feels like a solid buy, and the hex heads grab a socket perfectly.

Natalie ★★★★★

The PFC9 alloy steel feels more substantial than the zinc-coated hardware I've used before. The hex head engages my socket cleanly without any wobble.
