Dubro 4-40 Nylon Flat Washers RC Hardware - DUB635

The Dubro 4-40 Nylon Flat Washers (DUB635) are small-diameter hardware components designed for use with 4-40 threaded fasteners in RC aircraft builds and repairs. Nylon construction makes these washers lightweight and non-conductive, useful anywhere you need to protect surfaces, distribute load, or insulate between metal fasteners and composite or plastic airframe components. Each pack contains eight washers, giving you enough to cover multiple assembly points in a single build session.
