Customer Reviews (4.8 / 5 · 5 reviews)

Natalie Y. ★★★★★

I needed some sturdy set screws for a jig I was building, and these knurled cup points really grip the work surface without slipping. The alloy steel feels solid, and the hex socket drove smoothly even in a tight corner of my press frame.

Sofia ★★★★★

The hex socket drive made it easy to crank these down in a tight spot on my milling machine. Alloy steel feels plenty tough for the job, and the 50-pack means I won't have to reorder anytime soon.

Stella E. ★★★★★

The knurled cup point grips like a dream—I torqued these down on a jig plate and they haven't budged after a full shift of vibration. The hex socket made threading them into that awkward recessed spot way easier than slotted screws would have.
