Violet N. ★★★★★

Finally, a set screw that actually stays put under vibration. The hex socket drive lets me get full torque in a tight spot without stripping.

Joseph V. ★★★★★

The knurled cup point on these M4 set screws really grips well in the aluminum bracket I mounted. Alloy steel feels solid, and the hex drive makes tightening them in tight spots a breeze.

James ★★★★☆

Bought these for a small jig project and the hex socket drive made installation in tight spots much easier than I expected. The knurled cup point holds firmly without slipping.
