Specification

SEODescription

The Hex flange screw M5x45, compliant with DIN 6921 flange bolt M5 standards, is a metric fastener featuring a hexagonal head with an integrated flange for even load distribution. Designed as an M5x45 hex flange bolt, it has a 5 mm thread diameter, 45 mm length, and a flange diameter of 9.7 mm. Typically manufactured in steel or stainless steel with zinc-plated or Dacromet coatings, it operates in temperatures from -50°C to +120°C. This screw is widely used in automotive, machinery, and electronics for securing panels, brackets, or components. Its integrated flange eliminates separate washers, simplifies assembly, and provides vibration resistance. However, limited thread engagement may reduce effectiveness in high-stress applications. Compatible with standard M5 nuts and 8 mm hex wrenches.
