Viti a testa esagonale M16-2 x 230 mm | Acciaio classe 8.8 zincato | Filettatura parziale (10 / Confezione)

Used these to secure a heavy-duty press frame in my workshop and the 8.8 grade steel held up perfectly under load. The zinc plating looks clean and no rust after a week of assembly.

The hex head grabbed my socket wrench perfectly, no slipping even when I torqued it down tight on the equipment frame. Zinc plating's held up so far against a bit of moisture in the shop, and the partial threads made alignment a breeze. Exactly what I needed for this assembly job.

The partially threaded shaft made all the difference when I was bolting a heavy steel bracket to a concrete base, letting the threads grab just enough without binding. These M16s drove in smooth with a socket wrench and the zinc coating looks clean enough to handle a damp workshop.
