Customer Reviews (4.6 / 5 · 5 reviews)

Benjamin A. ★★★★★

Mounted a small gear onto a precision shaft with these set screws, and the 18-8 stainless steel feels solid and corrosion-resistant. The #4-40 threading engaged smoothly without any stripping.

Henry ★★★★★

The hex socket drive made it easy to torque these tiny #4-40 screws into a small gear hub without stripping. Nice to have a full pack of 200 for future projects too.

Christopher B. ★★★★★

Used a few of these #4-40 cup points to lock a small gear on a motor shaft, and the stainless steel feels solid enough for light industrial use. The socket drive made it easy to tighten with a hex key, even in a tight spot.
