The 402-907 is a Piper OEM aircraft bolt supplied in a pack of 10 pieces, used as a structural fastening component in various airframe and mechanical assemblies. Each bolt is designed to provide a high-strength, reliable clamping connection while maintaining alignment and load transfer under vibration, cyclic loading, and operational stresses.

In Piper aircraft applications, bolts like the 402-907 are commonly used in airframe structures, landing gear assemblies, flight control systems, engine mounts, and equipment attachment points, depending on aircraft model configuration. Their primary function is to ensure secure mechanical fastening and long-term structural integrity in critical assemblies.

These bolts are typically installed with compatible nuts, washers, and, where required, safety locking devices such as cotter pins or other locking methods to prevent loosening under vibration and dynamic loads. Proper torque application is essential to maintain airworthiness and joint reliability.

Manufactured to Piper OEM specifications, the 402-907 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 protect against environmental exposure and corrosion in aviation service conditions.

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