The 62833-043 is a Piper OEM aircraft washer used in structural and mechanical fastening applications across various Piper aircraft assemblies. It is a precision-specification hardware component designed to distribute load evenly in bolted joints and protect mating surfaces from damage caused by direct fastener contact.

In aircraft systems, washers like the 62833-043 are used in airframe structures, control system linkages, and landing gear assemblies, depending on aircraft model configuration. Its primary function is to maintain proper clamping force, reduce localized stress concentration, and improve long-term fastener reliability under vibration and cyclic loading conditions.

This washer is manufactured from corrosion-resistant aircraft-grade steel or alloy material, ensuring durability in environments exposed to moisture, temperature variation, and continuous mechanical stress typical of general aviation operations.

Although small, it plays an important role in maintaining correct hardware stack-up integrity. Using the correct washer specification is essential, as differences in thickness or material can affect torque values, preload characteristics, and overall joint performance.
