Customer Reviews (4.8 / 5 · 5 reviews)

Lily ★★★★★

I needed some small, durable screws for a metal bracket repair, and these #4-40 sem screws with the external tooth washer held tight without loosening. The cadmium finish looks clean and should resist corrosion well.

Ellie ★★★★★

The Phillips head seated perfectly on my driver without any stripping, and the cadmium finish has a nice uniform sheen that feels more durable than plain zinc. I used most of the 100 count for mounting brackets, and every single one threaded cleanly into the pre-tapped holes.

Daniel ★★★★★

Packed these screws up nicely for a small electronics project—the Phillips drive is clean, and the pan head sits flush against the surface.
