Customer Reviews (4.8 / 5 · 5 reviews)

Zoe ★★★★★

These set screws hold fast even in tight spots where a wrench won't fit; the hex drive lets me really crank them down. The cup point bites into the shaft nicely without stripping, which is exactly what I needed for a stubborn gear repair.

Andrew C. ★★★★★

Just swapped out a bag of mixed screws for these on a jig build, and the hex socket drive grabs perfectly even with my stubby Allen key in a cramped corner. The zinc plating has held up through a few weeks of shop use without any rust spots.

Daniel G. ★★★★★

I’ve been using these set screws in tight spots, and the hex socket drive gives me the torque I need without stripping. The alloy steel feels solid, and the zinc plating seems to hold up well—no rust after a few weeks in my shop.
