Washers

Washers, typically thin plates with a central hole, are commonly employed to distribute the load of fasteners like bolts, nuts, or rivets. Their versatility extends to usage as spacers, springs, wear pads, locking devices, electrical insulators, or for vibration reduction (e.g., rubber washers). Selection criteria encompass inside and outside diameters, thickness, plating, and material. Varieties include flat, external tooth, internal tooth, sealing, and split lock washers.
