Customer Reviews (5.0 / 5 · 5 reviews)

Miles ★★★★★

The Phillips drive on these #4-40 screws gripped the bit perfectly without any cam-out, and the zinc plating looks clean and consistent across all 1000 pieces.

Natalie ★★★★★

Used these to mount a small control panel to a metal enclosure, and the self-tapping action made quick work of the threads. The zinc plating looks clean and should hold up well against moisture.

John ★★★★★

The pan head on these #4-40 screws bites down flush without stripping, and the zinc finish has held up nicely through a few weeks of assembly work. For a thousand pieces at this price, the quality is surprisingly consistent across the whole batch.
