got a 12mm bolt, is this washer the right size for the sealing surface?
Question by: Roger W on Mar 11, 2026, 5:52 PM
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?
Question by: Phil C on Aug 27, 2025, 11:05 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.
