Product Description
The sp18c is a flat washer designed to distribute clamp loads and protect aircraft structure from fastener damage. This general-purpose washer provides a smooth bearing surface beneath bolt heads, nuts, and screws in airframe assemblies. Commonly specified where AN960 or NAS1149 flat-washer standards are called out in maintenance documentation.
Installation places the washer directly under the fastener head or nut per aircraft maintenance manual requirements and FAA AC 43.13-1B guidance. Used throughout airframe structures to prevent surface indentation and ensure even load distribution across riveted and bolted joints.
