Christopher W. ★★★★★

The Phillips drive on these M4 screws engages perfectly without any cam-out, and the pan washer head sits flush against my thin metal brackets. A full 300-pack for this quality is a real bargain.

Samuel ★★★★★

The pan washer head really does its job spreading the load on my sheet metal projects, and the Phillips drive bites cleanly without stripping. Grabbed a pack of 300, so I'm set for a while. The zinc coating has held up fine so far with no corrosion.

Edward W. ★★★★★

The trivalent zinc finish on these screws feels robust and corrosion-resistant, just what I needed for outdoor assembly. Each screw threads smoothly into pre-drilled holes without stripping, which saved me time on my project.
