The 402-915 is a Piper OEM aircraft bolt used as a structural fastening component in various airframe and mechanical assemblies. It provides a high-strength mechanical connection designed to clamp components securely while maintaining alignment and load transfer under vibration and operational stresses.

In Piper aircraft applications, bolts such as the 402-915 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 ensure a reliable joint that can withstand cyclic loading and environmental conditions encountered during flight and ground operations.

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 thermal cycling. Proper torque application is essential to maintain structural integrity and airworthiness compliance.

Manufactured to Piper OEM specifications, the 402-915 is generally made from high-strength aircraft-grade steel or alloy steel, often finished with corrosion-resistant coatings such as cadmium or zinc plating to enhance durability and protection in aviation environments.

Because it is used in structural or flight-related assemblies, correct installation, torqueing, and inspection are critical for safe operation and long-term reliability.
