Amelia ★★★★★

I needed these for a steel frame project and the hex washer head really helped distribute the load evenly while driving them in. The trivalent zinc finish looks clean and should hold up well against minor moisture.

William ★★★★★

Finally, some thread-cutting screws that actually bite into the metal without stripping. The hex washer head sits perfectly flush, and the trivalent zinc finish seems like it will hold up well in my outdoor projects.

Owen ★★★★★

Was looking for hex washer head screws for a metal roofing project and these self-tappers worked perfectly, the slotted drive held the bit steady. Count is generous for the price too.
