Olivia ★★★★★

I needed a small batch of knurled cup point screws for a vintage machine restoration, and the knurled grip really helps seat the hex socket securely. The zinc plating is consistent, with no chips or burrs out of the package.

Robert I. ★★★★★

I was worried about stripping such tiny screws, but the hex socket drive handles high-torque adjustment in tight spots perfectly. The zinc plating gives them a clean, consistent finish, and all 250 arrived in good shape.

Violet ★★★★★

The knurled cup point on these #4-40 set screws gives me a nice grip when I’m adjusting them in tight spots. I’m using a batch for a small jig, and the zinc plating already seems to be holding up well against minor rust. A solid pack for precision work.
