Hannah U. ★★★★★

Finally found machine screws that actually fit my equipment's 82° countersinks without sticking out. These #3-48 are precisely formed and the Phillips heads don't cam out like cheaper fasteners. Perfect for securing control panels where I need a clean, flush finish.

Isabella C. ★★★★★

I needed a bulk pack of small stainless fasteners for cabinet enclosures, and these #3-48 machine screws seat cleanly with a #2 Phillips bit every time. The 82° flat head sinks just below the surface without any mushrooming, even in thin sheet metal.

Benjamin ★★★★★

The 82° flat head sits perfectly flush in the counterbores on my aluminum enclosure, and the Phillips drive grabs cleanly every time. I’ve used about half the box on a few projects and haven’t had a single one spin out or deform.
