Product Description
The NAS143-5 is a high-strength plain washer manufactured from steel to NAS143 specifications. This washer distributes clamp load beneath bolt heads and nuts in airframe structural joints, providing a uniform bearing surface that prevents fastener embedment into composite or softer materials. Cross-referenced to MS20002-5, it's designed for demanding structural applications where load concentration must be minimized.
Installation follows aircraft maintenance manual torque specifications and hardware selection guidance for the specific joint application.
