M12-1.75 X 200mm Parafuso de Cabeça Sextavada | Aço Classe 8.8 Zincado | Rosca Parcial (20 Unid./Embalagem)

The partial threading on these M12 bolts made alignment much easier when bolting down a heavy support bracket. The hex head held up perfectly under my impact wrench, and the zinc coating looks clean and corrosion-resistant. Exactly what I needed for industrial assembly work.

The hex heads are machined cleanly, so my 19mm socket grips them without any wobble even after torquing them down. Threads ran smooth in the tapped holes with zero galling, and the zinc coating looks uniform across all twenty pieces.

Finally found some decent M12 bolts that are actually long enough for my frame jig — the 200mm length was exactly what I needed. The partial threading made it easy to get them seated in deep blind holes without binding.
