Product Description

The Hex Flange Screw M12x45, also known as the M12 Hex Flange Bolt, is a DIN 6921 M12x45 compliant fastener designed for high-stress applications in automotive, machinery, and construction industries. Featuring a hexagonal head with an integrated flange (washer face), this carbon steel or stainless steel screw eliminates the need for a separate washer. The M12x45 dimensions (12mm nominal diameter, 45mm shaft length) and serrated flange underside ensure vibration resistance and secure clamping. Typical tensile strength ranges from 8.8 to 12.9 grade, with optional zinc plating or anti-corrosive coatings. While offering excellent load distribution and tool compatibility with standard 19mm hex wrenches, its non-recessed design may require additional clearance in confined spaces.
