FastSeal

-More attractive, cleaner looking finish with a lower overall head height.
-No more over-installing so the bonded washer is distorted and made irrelevant and a better seal is made to the base metal.
-The encapsulated head protects the rubber washer from degradation.
-Since the washer is encapsulated the sealing aspect is enhanced eliminating concern about the integrity of the seal.
-Better and more consistent paint adhesion since the bonded neoprene washer is eliminated.
