Customer Reviews (4.8 / 5 · 5 reviews)

Lily V. ★★★★★

The partial threads grabbed perfectly when I mounted these on my press frame—no cross-threading at all, even with a socket wrench. Zinc coating looks uniform and should hold up fine in the shop.

Riley ★★★★★

Used these to bolt down a heavy-duty workbench leg bracket, and the 8.8 steel held tight under a lot of torque without stripping. The partial threading made it much easier to start the nut by hand.

Avery E. ★★★★★

The zinc plating on these M20 screws looks tough and even, which is exactly what I needed for outdoor equipment assembly. The hex head gave my socket wrench a solid grip without any slipping. These are holding up great so far.
