Steven C. ★★★★★

These little screws show up neatly organized, and the hex socket drive made setting them into a tight bracket surprisingly easy. The knurled cup point grabbed the shaft firmly with no slipping once torqued down. Exactly what I needed for the job.

James ★★★★★

I needed a secure grip on a small shaft repair, and these #4-40 set screws with the cup point really dig in. The hex socket drive made tightening them a breeze, even in a cramped spot.

Andrew ★★★★★

The knurled cup point bites into the shaft exactly where I need it, no slipping even after a few days of vibration. That alloy steel feels solid, and the zinc plating hasn't chipped during install.
