The Hartzell 6201003 Pin is a precision hardware component used in Hartzell aircraft propeller assemblies. It is designed to provide secure alignment and rotational support within propeller hubs or associated components.

Its primary functions include:

Maintaining precise alignment of propeller parts
Providing shear support for rotational and load-bearing applications
Ensuring secure assembly while allowing proper mechanical operation

Hartzell pins like the 6201003 are critical for the safe and reliable operation of propeller systems, helping to maintain balance, structural integrity, and proper function under operational stresses.
