got a 12mm bolt, is this washer the right size for the sealing surface?

Answer by: Customer Support on Mar 13, 2026, 6:41 AM

With a 12 mm internal diameter, it is meant to slip over hardware that matches that size and act as a sealing washer.

what's this washer made out of, and is it gonna hold up in a high-stress setup?

Answer by: Customer Support on Aug 29, 2025, 7:56 AM

Copper is the material here, which holds up well under demanding conditions. It handles both heat and electrical conductivity better than a lot of other common washer materials, so for high-stress sealing applications it tends to perform reliably over time. Brakequip built this one to be heavy-duty, so it's not a lightweight general-purpose part.
