Customer Reviews (4.6 / 5 · 5 reviews)

Jason ★★★★★

I needed hardened flat washers for a bench vice rebuild, and these M12s have a clean, uniform outer diameter that sits perfectly flush. No warping or burrs right out of the bag, just solid metal.

Sofia ★★★★★

Installed these on a bench vise and the hardened finish held up perfectly under heavy clamping loads. No deformation or galling even after a dozen adjustments.

Riley ★★★★★

The bore is perfectly centered, so it sits flat against the workpiece without any wobble. I've used it to shim a vise base and it hasn't deformed under repeated clamping pressure.
