WASHER (P/N an970-2) - New Surplus

The AN970-2 is a steel flat washer conforming to AN/NASM970 specifications. This large-area washer distributes clamp load under bolt heads and nuts, preventing localized crushing of airframe materials during fastening. Commonly installed in bolted joints throughout aircraft structures, particularly in wood substructures and composite assemblies where wide bearing surfaces are critical.

Install the washer directly under the bolt head or nut per aircraft maintenance manual requirements, then torque to specification. The expanded surface area of the AN970-2 reduces stress concentration at fastener interfaces.
