Customer Reviews (4.6 / 5 · 5 reviews)

Leo ★★★★★

Perfectly matched the 280mm length I needed for a heavy press repair — the partial threading gave enough grip without bottoming out. These bolts feel solid in the hand and the zinc coating looks clean and uniform.

Claire ★★★★★

I needed a partially threaded bolt for a heavy mounting bracket, and these M30x280mm hex heads fit the bill perfectly. The zinc plating looks clean and the class 8.8 steel feels solid enough for the job.

Charlotte ★★★★★

These are hefty M30 bolts, the zinc plating looks clean and the partial threading made it easy to start by hand before tightening with a socket. I used one to secure a heavy press base and the 8.8 grade gives me confidence it won't strip under load. Exactly what I needed for industrial assembly.
