Customer Reviews (5.0 / 5 · 5 reviews)

George K. ★★★★★

I needed bolts long enough to secure a heavy machine base, and these 220mm screws threaded perfectly with a socket wrench. The zinc coating on the partially threaded shaft looks clean and durable so far.

Zoe T. ★★★★★

These hex bolts drove in smoothly with a socket, and the zinc plating has a clean, uniform finish. The 220mm length was exactly what I needed for a heavy machinery bracket.

Henry ★★★★★

The partial threads made aligning these into a tight flange assembly so much easier than fully threaded bolts would have. They took a solid 160 ft-lbs without a hint of stripping, exactly what I needed for that heavy press frame.
