Emma ★★★★★

I needed some solid fasteners for a tooling jig I’m building, and these M20-2.5 x 80mm screws fit the bill perfectly—the partially threaded shaft made installation a breeze. They’re well made and feel strong enough for heavier assemblies.

George Z. ★★★★★

The hex socket drive on these M20 screws made installation straightforward with my allen wrench, and the zinc plating looks clean and durable. I used them for securing a heavy steel jig on a milling machine, and the partial threading allowed for a snug fit without bottoming out. Exactly what I neede

Joseph T. ★★★★★

The partial threading on these socket cap screws made aligning them in my jig a breeze, and the zinc plating looks clean and durable. They seated perfectly with a hex key and held tight under load.
