Customer Reviews (4.6 / 5 · 5 reviews)

Thomas ★★★★★

These are perfect for the jig I’m building—the class 10.9 alloy steel feels noticeably tougher than standard hardware, and the zinc plating gives them a clean, uniform finish without any burrs.

Amelia ★★★★★

I needed some strong fasteners for a jig project and these class 10.9 screws are definitely up to the task. The zinc plating looks clean and the hex socket drives smoothly without stripping, even under torque.

Mia Y. ★★★★★

These M8 button heads fit perfectly into my jig build, and the hex socket drive made installation a breeze with no stripping. The 55mm length was exactly what I needed for clamping down a thick bracket.
