Customer Reviews (4.8 / 5 · 5 reviews)

Stella ★★★★★

The knurled cup point on these set screws bites into the shaft just right, no slipping during assembly. Worked perfectly for securing a small pulley on a 3D printer axis.

William Z. ★★★★★

I needed a pack of these for a small robotics project, and the knurled cup point really grips the shaft without slipping. The hex socket drive makes them easy to tighten in tight spots.

David ★★★★★

The knurled cup point locks down tighter than I expected on this little #4-40, and the black oxide finish hasn’t chipped even after I swapped a few parts in and out. For a hundred pieces at this price, it’s hard to beat.
