Marine Fasteners RP-1438 1/4in Finish Washers 100-Pack

Marine Fasteners RP-1438 finish washers are stainless steel countersunk cup washers designed for use with flat-head or oval-head screws. These 1/4-inch washers provide a clean, professional appearance while protecting the mounting surface from screw head damage — an essential hardware item for marine, boat, and outdoor installations where a finished look is required.

Finish washers (also called finishing washers or countersunk washers) seat around the screw head, filling the countersunk recess and creating a polished, flush appearance on wood, fiberglass, and composite surfaces. Their corrosion-resistant construction makes them well-suited for saltwater and freshwater marine environments.
