An Auxiliary Drive Washer is a flat disc-shaped with a central hole that is used to distribute a load of a fastener, such as a bolt over a wider area, thereby reducing the pressure on the surface being fastened and preventing damage to it. It helps to adjust spaces, alignment, and fitment between the pulley and bolt.Attributes:• Hardened to Rockwell C scale hardness of 39 - 47, which determines it's resistant to deformation and wear• Withstands the shocks and vibrations encountered during the operationApplications:An Auxiliary Drive Washer helps to prevent the fastener from digging into the pulley or causing it to deform and ensures fine-tuning of the fitment of parts, compensating for slight variations in dimensions and achieving desired clearances.
