Customer Reviews (4.4 / 5 · 5 reviews)

Hazel ★★★★★

I was worried the partial threading might not hold tight enough, but the hex head grabbed perfectly with a socket wrench, and the zinc plating looks clean and rust-resistant. These are exactly what I needed for mounting a heavy jig to my drill press table.

Victoria ★★★★★

Finally got a proper M20 bolt with real thread length—the partially threaded design handled my heavy equipment bracket without any binding. Zinc plating looks clean and the hex head fits a standard wrench perfectly.

Edward ★★★★★

Finally, some M20 bolts that are actually the full 220mm length under the head. The hex head took a 30mm socket perfectly for torquing down on a heavy press frame.
