Lock Washers
Lock 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 keeps Lock Washers in stock and ready to ship, with fast 3-5 day shipping. Popular options include split lock washers, external tooth lock washers, and internal tooth lock washers.
Materials and Finishes
Lock Washers come in grades matched to the load, from carbon steel through high-strength alloy and corrosion-resistant stainless, with finishes from plain and zinc through hot-dip galvanized for outdoor and washdown service. Pair them with fasteners, USA-made, and environmental to round out the assembly.
How to Choose
Size it first with diameter, thread pitch, and length. From there, pick the grade that handles the load and a finish that matches where it will live, moving to alloy or stainless for high-stress or wet conditions.
