BOSS HDW01721 – 1″ ID x 2″ OD Washer
The Genuine BOSS HDW01721 – 1″ ID x 2″ OD Washer is a heavy-duty flat washer used primarily in the assembly and mounting of BOSS snowplows and ice control equipment. It is engineered to provide a large bearing surface, distributing the clamping load of fasteners across a wider area to prevent damage to the plow’s powder-coated surfaces.

Installation Note
When replacing hardware on your plow, it is recommended to use the specific BOSS part number rather than generic hardware store washers. Standard hardware may not have the same thickness or corrosion-resistant coating, leading to premature rusting or mechanical failure under the high-stress conditions of snow removal.
