Square ID Hole Washers | Carriage Bolt Washers

Square ID hole washers are used on square neck carriage bolts and square shafts. Carriage bolt washers feature square holes that allow for a fairly tight fit, as opposed to a round hole that would need to be much larger to slip over the corners of the square parts with which they’re assembled. The square holes also keep the carriage bolt washers from rotating in the square shaft.

Carriage bolt washers are available in a variety of materials, such as low carbon steel, stainless steel, brass, PTFE, nylon, and aluminum. We recommend choosing a square ID hole washer in a material that aligns with the specifications of your project. Carriage bolt washers are also available in a variety of finishes, such as zinc & clear, zinc & yellow, zinc & black, and phosphate & oil. Willie Washer stocks and distributes square hole washers that feature a variety of bolt sizes. Choose a carriage bolt washer with the bolt size that meets your needs.
