BSA Spring washer — exhaust pipe clamp bolt
A spring washer that goes under the bolt on an exhaust pipe clamp, keeping tension on the joint.
This is a spring washer used under an exhaust pipe clamp bolt. It's a small, simple hardware item, but it does a job that matters: keeping tension on the clamp bolt so the exhaust pipe stays snug at the port and doesn't work loose from engine vibration and heat cycling.
