Customer Reviews (4.6 / 5 · 5 reviews)

Adam T. ★★★★★

The 12.9 alloy steel feels incredibly dense and strong, and the zinc plating gives them a clean, uniform finish that resists rust. I used these to secure a custom jig for a milling project, and the threads bit cleanly with no binding. They're exactly what you want for heavy-duty tooling work.

Benjamin F. ★★★★★

The hex socket drive fits perfectly without any wobble, and the threads were clean all the way down. I used these to secure a heavy jig on our mill, and they tightened up to the rated torque without stripping.

Christopher ★★★★★

I was worried the 12.9 alloy steel might be brittle for my jig, but these M16 screws have held up perfectly under heavy use. The hex socket drive made installation a breeze with no cam-out issues.
