Viti a testa esagonale M36-4 X 140mm | Classe 10.9 Acciaio grezzo | Filettatura completa (10 / Pacco)

The hex head on these bolts took a 46mm wrench without slipping, which made tightening them in tight spaces straightforward. The threads cut cleanly into pre-tapped holes, so the assembly felt solid from the first turn. For a heavy machinery job, these held up exactly as expected.

I needed heavy-duty bolts for a large press build, and these fully threaded M36 screws seated perfectly in the tapped holes without any binding. The Class 10.9 steel feels sturdy enough to handle serious torque, and the hex heads gave my socket wrench a clean, snug fit.

These fit perfectly on the hydraulic press we're rebuilding, and the 10.9 grade steel means I don't worry about them shearing under load. The fully threaded length gave us plenty of engagement for a thick flange plate.
