Lucy ★★★★★

I needed some heavy-duty fasteners for a jig I was building and these fully threaded M24-3 screws fit perfectly—the zinc plating looks clean and hasn't shown any rust yet after a few weeks in the shop.

Eli Z. ★★★★★

The hex socket drive grips firmly without stripping, which is exactly what I needed for a precise machinery jig setup. These M24-3 x 80mm screws feel solid and the zinc plating gives them a clean, durable finish.

Michael ★★★★★

The flat head design sits perfectly flush in my jig, which is exactly what I needed for a tight assembly. The hex socket drive gripped firmly without any stripping, and the zinc plating looks clean. These 12.9 alloy screws feel solid for the price.
