DIN 6921 Hexagon Flange Bolt with Serrated Flange, Zinc Plated, Class 8.8 M8X25

Previous Next

Hexagon Flange Bolts with Serrated Flange, made from robust steel material with a resilient zinc plating surface treatment. These Class 8.8 flange bolts feature a hexagon head for optimal driving features. The right-thread direction and metric thread ensure a secure fit for a range of applications. The serrated flange design spreads built-up forces, reducing surface pressure, and provides excellent self-locking properties. Perfect for covering large or oversized holes without the need for washers, these bolts adhere to international standards including ASME ≈B18.2.3.4M, DIN ≈6921, ISO ≈4162 and EN ≈1665.

Info Specific features of hexagon bolts with serrated flange:
  • The flange enables built up forces under the bolt head to be spread over a larger area, consequently resulting in lower surface pressure.
  • The serrated flange rim gives excellent self-locking properties.
  • Large (oversized) holes and/or tooling holes can be covered by the flange.
  • Washers are not necessary.
  • Can be fully or partially threaded depended on length
