Short answer: Washers protect the joint: flat washers spread clamp load and shield soft surfaces, spring and lock washers resist loosening under vibration and structural washers carry heavy bolts, paired with supply from our Bolts and Nuts Supplier and the bolt view in our Bolt Buyers Guide.

Why Use a Washer
A washer spreads the bolt load, protects the surface and can lock the joint, with the bolt side in our Bolt Buyers Guide.
Flat and Fender
Flat washers sit under the head and nut while fender washers cover large or soft holes, with base stock in our Carbon Steel Supplier.
Locking Washers
Split and toothed lock washers bite the surface to stop vibration loosening, with the corrosion note in our Surface Finishing Guide.
Structural and Quality
Hardened structural washers carry heavy A325 and A490 bolts; verify lots with our Quality Inspection Guide and documents per our Mill Test Certificate Guide.
