Specification

SEODescription

The Hex flange screws M12x50, also referred to as M12x50 hexagonal bolts, are precision-engineered fasteners compliant with DIN 6921 flange screws standards. Designed with a 12mm diameter and 50mm length, these screws feature an integrated hexagonal flange head that eliminates the need for separate washers, ensuring stable connections in high-vibration environments. Constructed from grade 8.8 carbon steel or A2/A4 stainless steel, they support direct module mounting in industrial automation, transportation systems, and heavy machinery. The serrated flange underside enhances grip on surfaces, while zinc plating or galvanized finishes provide corrosion resistance. Operating effectively in temperatures from -30°C to +150°C, these bolts excel in automotive assembly lines and electrical enclosures. Their key advantages include space-efficient design and vibration resistance, though the hexagonal profile may require specific torque tools for proper installation in confined spaces.
