Samuel ★★★★★

The zinc plating on these #4-40 sem screws is nice and even, no burrs or residue that I've had with other packs. They drive smoothly into sheet metal with a standard phillips bit, and the built-in lock washer is a real time saver on assembly jobs.

Timothy ★★★★★

Needed a batch of small fasteners for mounting control panels and these #4-40s fit perfectly. The internal tooth lock washer already attached saves so much time on assembly.

Michael ★★★★★

The zinc plating on these little pan heads is evenly applied and they drive clean without stripping. I've worked through about half the box on a shelving project and every single screw threads smoothly into the pre-drilled holes.
