Abstract: A fastener cap system can include a rigid cap and a sealing member which forms a liquid barrier so moisture is impaired from entering a space under the rigid cap and/or around a fastener installed through it. The sealing member can include a central seal disposed on an upper surface of the cap, the seal extending beyond a head of a fastener, which extends through the cap and sealing member, so that moisture is impaired from entering the cap under the head.

The sealing member, which can have a higher coefficient of friction than the rigid cap, thereby does not drag along a cap feeder and cause feeding issues. Related methods of manufacture and use are provided.
