Owen L. ★★★★★

The hex head on these M30 bolts let me torque them down properly with a socket without any cam-out. The zinc plating seems tough, and the full threading gave me plenty of grip in the heavy steel bracket I was installing.

Abigail ★★★★★

These bolts fit perfectly into the flange mounts on my press jig, and the zinc plating on the 8.8 steel already feels tougher than cheaper hardware I've used. Having them fully threaded gave me plenty of grip depth for the heavy clamping force I needed.

Isabella H. ★★★★☆

Picked these up for a heavy equipment assembly job and the zinc plating gives them a nice, uniform finish that should resist rust. The 70mm length worked well for the application, though I wish the threads were a bit cleaner right out of the pack. Solid fasteners for the price.
