Slotted Square Washers



Slotted Square washers are square plate washers with a slot instead of a traditional hole. Slotted Square washers are designed to be added to bolts or shafts that are already partially assembled. These washers are commonly used where frequent maintenance is required, as they can be removed and replaced without disassembly. Slotted Square washers are also known as body shims or body shim washers in the automotive industry because of their use with body work. Slotted Square washers are also utilized in applications where movement prevention is essential because the square OD prevents parts from rotating.
