Riley M. ★★★★★

I needed some high-strength fasteners for a heavy jig I'm building, and these M16-2 x 55mm screws fit perfectly. The hex socket drive made installation much easier than using external wrenches, and the 12.9 alloy steel feels incredibly solid.

Hannah ★★★★★

The black oxide finish held up perfectly when I tightened them into my jig plate, no galling at all. Thread engagement felt precise and they seated flush without any wobble. Exactly the strength I needed for a heavy-duty assembly.

Carter I. ★★★★★

These fit perfectly in my jig fixture, and the hex drive made torquing them down easy. For the price, getting 50 pieces in this alloy steel feels like a solid value for shop use.
