Product Description
The 302-0640-130 is a nonmetallic insulating washer for aircraft fastener assemblies. This component provides electrical isolation between bolts or nuts and conductive structures, preventing galvanic corrosion and interrupting unwanted current paths. Commonly installed under fastener heads on avionics equipment, antenna mounts, and electrical system connections.
The washer's nonmetallic construction—similar to NAS549 or NAS1515 specifications—maintains dielectric properties while accommodating standard aerospace bolt sizes. Installation follows aircraft maintenance manual requirements and FAA AC 43.13-1B accepted practices for fastener joint assembly.
