Chloe B. ★★★★★

The black oxide finish on these screws is a nice touch—they slip into counterbores without binding up like plain steel ones often do. I’ve used about half the pack for a fixture rebuild and none have stripped or snapped. Solid choice for shop work.

Robert ★★★★★

I needed a batch of flat heads for a jig rebuild and these seated perfectly without any mushrooming. The hex socket drive made installation quick with just a standard Allen key.

Joseph ★★★★★

The thermal black oxide finish on these screws feels much more durable than plain steel, and the hex drive seated perfectly without stripping. I used them for a press fixture and they held torque exactly as needed.
