Customer Reviews (5.0 / 5 · 5 reviews)

Henry ★★★★★

The hex socket drive made tightening these in my machine’s tight spots a breeze, and the cup point really digs in securely. Perfect for a high-torque adjustment I needed on a jig.

Kevin V. ★★★★★

The zinc plating on these screws looks clean and even, and the cup point grips securely without slipping during assembly. For the price, getting 250 pieces in one pack feels like solid value for any shop.

Zoe X. ★★★★★

The hex socket drive made installing these in my jig fixtures a breeze, even in those cramped spots where a wrench wouldn't fit. The cup point tip seated perfectly and hasn't stripped under repeated use.
