Customer Reviews (4.8 / 5 · 5 reviews)

Penelope S. ★★★★★

The zinc plating on these screws looks clean and uniform, which is a nice bonus for a functional fastener. They fit perfectly into pre-tapped holes on my metal enclosure without any stripping. Exactly what I needed.

Amelia ★★★★★

Just got these for a project replacing a few enclosure panels, and the hex head makes them easy to tighten with a socket. The zinc plating looks even and should resist rust. Exactly what I needed for the job.

Scarlett ★★★★★

The zinc plating on these machine screws seems really durable, and the hex head makes it easy to get good torque with a standard wrench. I used them to mount some steel brackets in a metal enclosure, and they threaded perfectly without stripping.
