Customer Reviews (4.6 / 5 · 5 reviews)

Isabella E. ★★★★★

These 12.9 grade screws are seriously strong; I used them on a drill jig and the flat head seated perfectly flush. The zinc plating looks good and the hex socket drove cleanly without stripping.

William P. ★★★★★

I needed some heavy-duty screws for a jig I’m building, and these M20s fit the bill perfectly—the hex socket drive makes them easy to tighten without stripping. The zinc plating seems durable, too.

Natalie ★★★★★

These held up perfectly under heavy torque when I was bolting down a new press brake die. The zinc plating on the 12.9 alloy steel looks clean and corrosion-free so far.
