Brass Washers

Brass Washers sit under a bolt head or nut to spread the clamp load and protect the work surface. The right washer protects the joint, spreads the load, and keeps the fastener from working loose over time. South Coast Fasteners stocks Brass Washers in a full range of sizes, grades, and finishes, with fast 3-5 day shipping.
