Description

Hexagon Flange Bolts with Ribbed Flange, made from robust steel material with a zinc flake finish which is free from hexavalent chromium (Cr6+) and compliant to ISO 10683 surface treatment. These Class 100 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 ribbed 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 DIN ≈6921.
