Brian M. ★★★★★

The black oxide finish on these cup point screws is a nice touch — they slide into tight spots without any glare. Worked perfectly for securing a small gear on a threaded shaft.

Natalie M. ★★★★★

I needed some precise #4-40 set screws for a small shaft collar repair, and the cup point really bit into the metal firmly without slipping. The black oxide finish is a nice touch—keeps them looking clean and prevents surface rust in my tool box.

Andrew ★★★★★

The hex socket drive made these easy to torque into place with a tiny Allen wrench, even in a tight spot. The thermal black oxide finish has a nice matte look and they seated firmly without any stripping. Exactly what I needed for securing a collar on a small shaft.
