Customer Reviews (4.8 / 5 · 5 reviews)

Hazel C. ★★★★★

I've used dozens of set screws for securing pulleys, and these M3 x 3mm ones from this batch are the first that actually stay tight under vibration—the cup point bites into the shaft exactly as needed.

Ruby ★★★★★

The cup point digs in perfectly on my motor shaft—no slipping at all. Alloy steel feels solid and the threads were clean on every single screw in the pack. Exactly what I needed for securing a small gear.

Owen ★★★★★

Used a bunch to secure a pulley to a small motor shaft, and the cup point bit into the steel perfectly without slipping. The alloy steel feels plenty hard for this kind of job, and the 200-count box is great to have on hand.
