Natalie ★★★★★

The zinc plating on these M20-2.5 x 160mm screws looks even and hasn't chipped when I've torqued them down in my jig setup. The hex socket drive seats perfectly with my Allen key, and the partial threading makes alignment a lot easier than fully threaded options.

Ruby ★★★★★

The threading is clean and precise, making them easy to start by hand before wrenching down. They torqued to spec without any issues on my press tooling assembly.

Scarlett H. ★★★★★

Needed these for a jig I was building, and the 12.9 grade steel feels incredibly tough—way stronger than the hardware I usually grab. The zinc plating is smooth and even, which is nice for corrosion resistance in my shop.
