The 62833-086 is a Piper OEM aircraft washer used in structural and mechanical fastening applications across various Piper aircraft assemblies. It is a precision-specification load distribution component designed to be installed under bolt or nut heads to ensure even force distribution and protect mating structural surfaces.

In aircraft construction, washers like the 62833-086 are essential for maintaining correct fastener performance in vibration-prone environments. They help prevent localized stress concentration, reduce fretting between components, and support consistent torque retention in airframe, landing gear, and control system assemblies depending on installation location.

This washer is manufactured from aircraft-grade corrosion-resistant steel or equivalent alloy material, selected to withstand long-term exposure to environmental conditions, cyclic loading, and mechanical vibration encountered in normal aircraft operation.

Although small, this part plays an important role in maintaining joint integrity within certified aircraft hardware stack-ups. Proper washer selection is critical, as incorrect thickness or material can affect preload, torque values, and long-term structural reliability.
