Screw washers are disc-shaped pieces used with screws and bolts to distribute load, reduce friction, and protect surfaces.
Common types:
Metal - Basic steel, aluminum, or brass washers. Inexpensive, smooth surface prevents damage and sticking. Sizes from 1/4 to several inches.
EPDM - Synthetic rubber washers. Flexible, cushion vibrations, conform to uneven surfaces. Resist weathering and corrosion. Used where vibration is a concern.
Bonded Metal-EPDM - Metal washer laminated with EPDM rubber. Combines strength with vibration dampening. Used on equipment with high vibration like exhaust systems.
Roofing - Metal-EPDM washers commonly used with roofing screws for waterproof, durable seals.
Choosing the right washer type is key for optimal fastener performance. Each offers specific advantages depending on the application. Overall, washers strengthen connections and extend service life.
