Applications & Selection Guide

ISO 898-1 property class 10.9 hex flange bolts to DIN 6921 / EN 1665. One-piece bolt with a washer flange under the hex for high-preload joints that should not carry a loose washer. Metric coarse, listed M4–M12. Not an HV structural bolt.

Specify 10.9 flange bolts when the joint needs higher clamp and a captured washer face. Mate with class 10 flange or hex nuts. Confirm coating practice for 10.9. Not for pretensioned building connections — those use HV sets.

Request a quote with M×L sizes, quantities, surface finish, and delivery country. Matching class 10 flange nuts can be added.
