Product Description
The MS172209 is a key washer conforming to Military Standard MS1722 specifications for aircraft fastening applications. This steel washer features integral keys that engage a shaft keyway to prevent fastener rotation under vibration and dynamic loads. Installed beneath bolt heads or nuts on shafted assemblies and retainers, the washer locks the fastener in place while the keys resist circumferential movement.
Cross-referenced to MD Helicopters part 369D21813-1, this washer is essential in helicopter and fixed-wing aircraft where vibration-resistant fastening is critical.
