The 494-081 is a countersunk washer designed to seat flat-head fasteners flush with airframe surfaces. This washer distributes bearing loads across access panels, skin joints, and structural assemblies while maintaining a low aerodynamic profile. Installed beneath countersunk screws, it protects softer substrates from fastener pressure and prevents surface damage during assembly and maintenance.
The washer conforms to MS20002 and NAS1587 standards for countersunk applications. Installation follows aircraft maintenance manual specifications and standard aerospace fastening practices for Piper and similar aircraft designs.
