Product Description
The MS21042L8 is an all-metal self-locking hex nut with an extended washer flange, designed for aerospace fastening applications requiring prevailing-torque retention. Conforming to MS/NASM21042 specifications, this reduced-height locknut prevents fastener loosening from vibration and thermal cycling. The extended flange distributes clamping load across larger surface areas on airframe structures, panels, and system brackets.
Installation requires matching the dash size to thread compatibility and applying torque per aircraft maintenance manuals. Observe NASM33588 limitations for self-locking nut reuse and replacement cycles.
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.
