The 62833-087 is a Piper OEM aircraft washer used in structural and mechanical fastening assemblies across various Piper aircraft models. It is a precision-specification hardware component designed to distribute load evenly across a bolted joint, helping maintain proper torque retention and preventing damage to the mating surfaces.

In aircraft applications, washers such as the 62833-087 are used wherever bolts, screws, or studs secure structural components, control systems, or equipment mounts. Its role is to reduce point loading, minimize wear, and ensure consistent clamping force in vibration-prone environments such as airframe structures, landing gear attachments, and control linkage assemblies.

This washer is manufactured from corrosion-resistant aircraft-grade steel or alloy material, selected to withstand repeated cyclic loads, environmental exposure, and long-term operational stress typical in general aviation service.

Although small and inexpensive, it is a critical part of the fastener stack-up, ensuring correct assembly behavior and long-term structural integrity. Substituting with non-approved hardware can affect torque values and joint performance, potentially impacting airworthiness compliance.
