Customer Reviews (4.6 / 5 · 5 reviews)

Matthew ★★★★★

Needed a long set screw for a tricky alignment job, and the 4" length was exactly what I needed. The cup point held firm against the shaft without slipping under heavy torque, and the hex socket made driving it easy in a super tight spot.

Sebastian ★★★★★

I was pleasantly surprised at how well the hex socket drive bit fits—no wobble at all when tightening these in a tight machinery spot. The stainless steel feels solid, and the cup point grips firmly without stripping.

Abigail M. ★★★★★

These set screws worked perfectly for securing a pulley on a shaft where vibration was an issue. The cup point bit into the metal nicely, and the hex drive made installing them in a cramped spot a breeze.
