Daniel ★★★★★

I've been using these #4 thread cutting screws for mounting small brackets, and the trivalent zinc finish is holding up well without rust in my damp basement. The Phillips drive bites nicely without stripping, even when driving into harder plastics. A solid choice for precision assembly work.

Adam ★★★★★

The fillister head on these #4s grabs the driver better than any pan head I've used, and the trivalent zinc coating looks clean and uniform across all 5000 pieces. Sorted through a handful for a small electronics bracket job and every single one cut threads smoothly into the steel without snapping.

George ★★★★★

I needed these tiny #4 screws for a delicate electronics project and the trivalent zinc finish feels nice and corrosion-resistant. The fillister head gave my driver a solid bite without stripping. Exactly what I needed for tight spaces.
