Product Description
The 557316 is a steel lock washer conforming to MS35338 specifications (formerly AN935). This washer maintains clamp load and prevents fastener loosening caused by vibration in aircraft structural assemblies. Installed under bolt heads or nuts on airframe mounts, it provides spring tension to resist vibration-induced rotation.
The washer's deformed teeth grip against mounting surfaces, creating friction that locks the fastener in place during flight operations. Select the correct size per the aircraft's Illustrated Parts Catalog and install per maintenance manual torque specifications.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
