Abstract
An apparatus and method for roughening or otherwise changing the gasket face of a bolt-like header plug. This apparatus utilizes a cutting or etching tool that cuts into the originally flat gasket face. A threaded shank formed by a lathe or other screw cutting machine extends from the face and is not useable for modifying the face. Roughening or otherwise modifying of the gasket face is in the form of grooves cut into the face so as to increase the sealing effect of the header plug when in use.
