Owen U. ★★★★★

The socket drive on these #4-40 screws gave me a solid grip without stripping, and they fit perfectly for securing a small pulley to a shaft. I’ve already used a dozen from the pack and they hold tight under moderate torque.

Ava ★★★★★

The cup point bites into the shaft nicely, so these little set screws hold my collars firmly without slipping. The alloy steel feels plenty tough for the size, and having 200 in one package means I'm set for many projects to come.

Lucy A. ★★★★★

Needed a bunch for securing a tiny pulley on a model shaft, and the alloy steel feels noticeably tougher than the brass ones I've tried before. The cup point grips the shaft nicely without stripping.
