Product Description
The MS21042-5 is an all-metal, self-locking hex nut with an extended washer base designed for vibration-resistant fastening. This prevailing-torque nut features a 5/16-24 UNJF thread and uses internal locking features to prevent loosening under aircraft vibration and thermal cycling. The extended washer distributes load across a wider surface area, reducing stress concentration on airframe structures and panel attachments.
Install to specified torque values and verify prevailing-torque resistance per the aircraft maintenance manual before service.
