Customer Reviews (5.0 / 5 · 5 reviews)

Aurora D. ★★★★★

The threads cut cleanly into the tapped hole without any binding, and the fully threaded length gave me plenty of grip for a thick flange assembly. Class 8.8 steel feels solid under torque, and the plain finish looks just right for indoor gear. These are my go-to for heavy machinery repairs now.

Carter ★★★★★

The hex head grabbed my socket wrench perfectly without any slipping, which made tightening these M22 bolts into my press frame much smoother. For the price of a 20-pack, the class 8.8 steel feels solid and consistent across every screw. Exactly what I needed for heavy machinery repairs.

Zoe ★★★★★

Installed these on a heavy-duty jig I'm building and the hex head held up perfectly under high torque without stripping. The 8.8 steel gives me confidence it'll last, and the 55mm length was spot on for my application.
