Product Description

The MS14144-4 is a self-locking castellated hex nut designed for 1/4-28 UNJF-3B threads. Manufactured from steel with an all-metal prevailing-torque locking mechanism, this nut prevents loosening under vibration and thermal cycling without requiring safety wire or additional fasteners. The extended washer design distributes load across a wider surface area, reducing stress concentration on composite or thin-gauge materials.

Used in structural and systems assemblies where positive locking and compact design are required. Installation follows MS14144/NASM14144 specifications and aircraft maintenance manual torque procedures.

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.
