Product Description

The Cylindrical head M12x55 screw, compliant with DIN 912 M12x55 standards, is a hex socket screw designed for high-torque applications in machinery, automotive, and structural engineering industries. Featuring a cylindrical head with a 12mm diameter and 55mm length, it requires an 8mm hex key for installation. These M12x55 hex socket screws are typically manufactured from grade 8.8 or 12.9 steel, offering tensile strengths up to 1200 MPa, and can withstand operational temperatures ranging from -50°C to +150°C. The DIN 912 M12x55 screws provide vibration-resistant fastening in compact spaces due to their low-profile head design. Key advantages include corrosion resistance (with optional zinc or chrome plating), high shear strength, and compatibility with standard M12 nuts. Limitations include restricted accessibility in deep recesses. Commonly used in engine components, industrial equipment assembly, and steel framework connections.
