ABSTRACT:
An improved spark plug gasket particularly adapted to be installed in locked relation upon a spark plug body of a type having a fully threaded shank. The gasket includes the usual sealing flanges and a plurality of inwardly extending locking members or tabs which are staked directly against the threads of the shank adjacent the base portion thereof. A wedge-like staking tool engages the locking members as it is inserted in an interstice between the sealing flanges and the locking members to radially inwardly force the locking members against the threads on the shank, and deform the locking members to at least partially conform to the threads.
