0 Flat Washer. These general use flat washers are positioned under the head of a bolt or nut in order to provide a smooth bearing surface and distribute the fastener load over a wider area. General purpose steel flat washers are primarily used in every day applications and are utilized in dry environments.
Flat washers protect surfaces by evenly distributing torque when a bolt or screw is tightened. The combination of internal and external teeth boosts gripping power to maintain a tight hold and provide more vibration resistance than other tooth lock washers. Flat washers protect surfaces by evenly distributing torque when a bolt or screw is tightened.
With greater diameters and/or thicknesses than general purpose washers, these washers cover oversized holes or act as spacers and levelers.
Also known as plain washers, these plastic washers are among the most commonly used.
They are designed for general purpose and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners. Flat washers protect surfaces by evenly distributing torque when a bolt or screw is tightened. Use with fasteners that have heads large enough to make contact with the external teeth, such as pan, button, and binding head screws.
