The 402-911 is a Piper OEM aircraft bolt used as a structural fastening component in various airframe and mechanical assemblies. It is designed to provide a strong, reliable clamping connection between components while ensuring proper alignment and load transfer under vibration, cyclic loading, and operational stresses.

In Piper aircraft applications, bolts such as the 402-911 are commonly used in airframe structures, landing gear assemblies, flight control systems, engine mounts, and equipment attachment points, depending on aircraft model configuration. Its primary function is to maintain secure mechanical fastening and long-term structural integrity in critical assemblies.

This bolt is typically installed with matching nuts, washers, and where required, safety locking devices such as cotter pins or locking features to prevent loosening due to vibration or dynamic loads. Correct torque application is essential for maintaining airworthiness and joint reliability.

Manufactured to Piper OEM specifications, the 402-911 is generally made from high-strength aircraft-grade steel or alloy steel, often with corrosion-resistant coatings such as cadmium or zinc plating to protect against environmental exposure and corrosion in aviation service conditions.

Because it is used in structural or flight-critical applications, proper installation, torqueing, and inspection are essential to ensure safe operation and long-term reliability.
