Product description

The Coats 84398637 is a genuine OEM flat washer measuring 12mm internal diameter x 21mm outer diameter x 2.5mm thickness, used as a mechanical spacer and load-distribution component in Coats tire changers and wheel balancers. This precision-machined stainless steel washer evenly distributes clamping loads and reduces surface friction at bolted joints and pivot points, helping prevent premature wear on mating hardware. As a small but essential OEM fastener component, replacing a worn, corroded, or missing washer with this genuine part restores proper torque retention and mechanical alignment on compatible Coats equipment assemblies.
