Product Description
The 494-281 is a plain washer for aircraft fastener assemblies. It provides a smooth bearing surface beneath bolt heads and nuts, distributing load across a wider area to prevent fastener pull-through on thin materials. Used in airframe structural joints and control surface attachments, this washer aligns with AN960/AN970 specifications referenced in FAA AC 43.13-1B.
Install the washer between the fastener and structure, positioning it to allow proper nut rotation for cotter pin alignment in castellated nut applications. Follow aircraft maintenance manual guidance for torque and installation sequence.
