Clips and Fasteners has every type of nut, bolt and fastener you could ever need, including
auto copper exhaust fasteners. Copper plated car nuts don’t move around when exposed to
the extreme heat of the exhaust system, making them ideal for exhaust manifolds. Copper
exhaust flange nuts don’t corrode or bond to other metals, and the plating won’t flake off after
multiple heat cycles, unlike galvanized nuts.
We carry copper exhaust lock nuts in several common sizes, including M8-1.25, M10-1.25,
and JIS M10-1.25. These copper plated exhaust nuts have a steel core, so they’re less likely to
strip than solid brass nuts
