Product Description

The Hex flange screws M6x18, compliant with DIN 6921 flange bolts standards, are stainless steel hex flange bolts designed for robust mechanical and structural applications. These screws feature a hexagonal head with an integrated flange, eliminating the need for separate washers, and are commonly used in automotive, construction, and industrial machinery sectors. Constructed from corrosion-resistant A2/A4 stainless steel, they operate effectively in temperatures ranging from -50°C to 300°C and withstand harsh environments. The M6x18 dimension ensures compatibility with standard mounting interfaces, offering high tensile strength (up to 800 MPa) and secure fastening. Advantages include superior durability, resistance to oxidation, and simplified installation. A potential drawback is reduced suitability for ultra-high-torque applications compared to hardened steel variants. Ideal for assembly requiring vibration resistance and long-term reliability.
