Zamp M6 Circle Vent Qty 12 Plugs

Twelve black M6 insert plugs in one pack. They cap off the M6 inserts on your Zamp helmet — the threaded points for head-and-neck restraints — when nothing's bolted in.

Plugs keep dirt and dust out of the threads and tidy up the shell. Cheap insurance for a set of inserts you don't want seizing up between races.
