Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

Finally got these for a project where I needed that precise 7/8" length—they thread into pre-tapped holes with zero fuss. The zinc coating looks even and should hold up fine in my garage.

Avery ★★★★★

I needed a full box for a small electronics project, and these #4-40 screws hold panels tightly without stripping. The phillips drive bit fits cleanly every time, and the trivalent zinc finish looks good under the hood.

Penelope ★★★★★

The flat 100° head sits perfectly flush in my panels, and the trivalent zinc finish gives them a clean look that resists rust. I've been using these for mounting metal brackets, and the 5000 count means I won't run out anytime soon.
