Frequently Asked Questions
What is the 6I0563 nut used for?
The 6I0563 nut threads onto a bolt or stud to create and hold clamp load, locking the joint together against vibration. The right nut keeps a fastened assembly secure.
How do I install the 6I0563 nut?
Fitting the 6I0563 correctly comes down to clean surfaces and following the manual sequence. Work through these steps:
- Shut the machine down and isolate power before service
- Clean the threads on the stud or bolt and inspect them
- Thread the 6I0563 on by hand to confirm it runs freely
- Tighten to the specified torque in the correct sequence
- Re-check the torque after the first operating cycle if advised
