| Using a jam nut on a shaft collar set screw creates a pulling force opposite the pushing force of the screw and should be avoided. |
Stacking one set screw atop another can cause head damage and is not recommended. | Stacking a socket jam screw atop a set screw is the best mechanical locking method. |
