Matthew ★★★★★

These set screws are perfect for locking pulleys onto a motor shaft. The hex drive makes seating them deep into a tapped hole straightforward, and I appreciate the tight, consistent threads across all 100 pieces in the pack.

Nicholas ★★★★★

The knurled cup point really bites into the shaft, holding fast without slipping. I've used several already for positioning a gear and they haven't loosened at all. Exactly what I needed for a clean, secure fit.

John ★★★★★

Installed these to secure a pulley on a motor shaft and the knurled cup point bit in nicely without slipping. The hex drive seated firmly in the socket with no wobble, and the 100-pack means I have plenty for future projects.
