Customer Reviews (4.8 / 5 · 5 reviews)

Ella ★★★★★

The knurled cup point gives these screws a really nice, finished look on my project. They seated perfectly with a hex key and the alloy steel feels solid, no stripping so far. Exactly what I needed for this assembly.

Scarlett ★★★★★

The hex socket drive makes installation a breeze, even in tight spots, and the knurled cup point grips steel firmly without slipping. These alloy steel screws have held up perfectly under heavy vibration in my machinery.

Henry A. ★★★★★

These set screws have a nice sharp cup point that locks down tight on my shafts. The hex socket drive makes them easy to install even in awkward spots, and I appreciate the knurling for grip during adjustment.
