Product Description

The M6x45 flange screws, also known as Hex flange bolts M6x45 or DIN 6921 M6 screws, feature a hexagonal head with integrated washer-like flange for secure fastening in industrial applications. These 6mm diameter screws with 45mm shaft length comply with DIN 6921 standards, offering 8.8-grade tensile strength and zinc-plated corrosion resistance. The integrated flange distributes clamping force across 11mm diameter, eliminating separate washers. Ideal for machinery assembly, automotive components, and structural frameworks, they operate in -30°C to +120°C environments. Advantages include vibration resistance and simplified installation, though requiring 10mm wrench clearance. Typical torque specifications range 9.6-10.9Nm for steel-to-steel connections. Their compact design suits space-constrained applications in manufacturing and construction sectors.
