Customer Reviews (4.6 / 5 · 5 reviews)

Sofia Q. ★★★★★

The knurled cup point really grips the shaft without slipping, even under vibration. These #6-40 screws are exactly the right size for my small jig adjustments.

Richard ★★★★★

I needed set screws with decent grip for a tight panel area, and the hex socket drive on these makes adjusting them in cramped spots a breeze. The alloy steel feels sturdy and should hold up fine.

Avery Q. ★★★★★

These set screws are exactly what I needed for a small mechanical adjustment on my lathe. The knurled cup point grips the shaft tightly without slipping, and the hex socket made installation in a tight spot a breeze.
