Hot-Dip Galvanized (HDG) M12 × 50 mm hex-head bolt with matching nut—designed for strong, corrosion-resistant fastening in industrial and outdoor applications
This fastener set includes an M12 bolt with a 50 mm length and a corresponding hex nut, typically accompanied by flat and spring washers. The carbon steel components are treated via hot-dip galvanizing for enhanced corrosion resistance. Available in mechanical strengths like Grade 4.6 or higher. Conforms to ISO/DIN standards (e.g., ISO 4017 / DIN 933 for bolts and ISO/DIN for nuts). Ideal for use in construction, structural supports, solar arrays, and electrical hardware
