A spring washer, also known as a split washer or lock washer, is a type of mechanical fastener used to prevent a nut or bolt from loosening due to vibrations or other external forces. It is typically made from a spring steel material and features a circular shape with a small gap or split. When the washer is compressed, it exerts a spring force against the nut or bolt, helping to maintain tension and preventing slippage.
Shape: It is generally a flat washer with a split or gap in the ring. The gap causes the washer to apply pressure when it is compressed between the bolt head or nut and the surface.
Material: Typically made from high-carbon steel, stainless steel, or other spring steel alloys to maintain tension and provide durability.
Function: The main function of a spring washer is to prevent loosening of fasteners in applications where vibration, expansion, or contraction is a concern. It also helps distribute load evenly across the fastened surface.
Internal Spring Washer: These are placed inside a nut or bolt head to help keep the fastener in place.
External Spring Washer: These are placed under the nut or bolt to provide a locking effect on the surface.
Automotive industry: Used to secure bolts and nuts in places subject to vibration.
Construction: Commonly used in structural assemblies where vibration is a concern.
Electrical: Can be used in electrical equipment to prevent loose connections.
Machinery and equipment: Often employed to keep components firmly in place.
Spring washers are a simple and cost-effective solution for preventing fasteners from loosening, improving the reliability of the assembled product.
