Choose what fits your repair or installation job. Larger pack sizes help keep this common hardware size available for future service work. Description These oil resistant nitrile rubber flat washers provide a flexible cushioning interface between metal hardware and mounted components in automotive and powersports applications. Designed for 5/16" hardware, these washers help reduce metal-to-metal contact under bolt heads and brackets while protecting painted, plated, and coated surfaces during installation and service work. The 1" outside diameter distributes load across a wider surface area for improved mounting stability on fairings, skid plates, battery trays, brackets, and chassis hardware. Nitrile rubber construction performs well in engine bay and garage environments where oil mist, grease, vibration, and repeated service conditions are common. Commonly used in motorcycles, ATVs, UTVs, automotive trim mounting, small engine equipment, fabrication projects, and general repair applications. Material properties are provided for general reference only. Buyers are responsible for verifying suitability for their specific application.
