Jason ★★★★★

Phillips drive seats the driver without cam-out, which saved me a ton of frustration on a tight assembly job. These cut their own threads cleanly into the steel bracket, and the 2000-count box means I’ve got spares for years.

Michael ★★★★★

The black oxide finish on these is holding up well, no rust after a few months in my shop. They thread into pre-tapped holes effortlessly and the pan head sits flush.

Jason ★★★★★

I've been using these #4-40 x 3/8" screws for electronic enclosure assembly, and the Phillips drive makes installation clean and hassle-free. The pan head sits flush without marring surfaces, and the 2000-count package is a fantastic value for large projects.
