Metric Flat Washers

Metric Flat 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 Metric Flat Washers in stock and ready to ship, with fast 3-5 day shipping. Popular options include alloy steel metric flat washers, zinc plated metric flat washers, and plain steel metric flat washers.
