Lift-the-DOT Washer 90-BS-16509-1A Nickel-Plated Brass 100 pack offers a secure fastening solution designed for outdoor and marine fabric applications. Made of corrosion-resistant nickel-plated brass, these washers lock firmly on three sides and release by lifting the fourth side, ensuring a reliable hold that prevents accidental opening. Ideal for use with matching studs or sockets, they are heavy-duty enough for demanding settings like boat covers, upholstery, outdoor gear, and marine hardware. This pack of 100 washers is well-suited for enhancing patio décor or outdoor living spaces by providing a durable, rust-resistant fastener that excels in cloth-to-cloth attachment.
