Frequently Asked Questions
Q: What is a castle nut and what does it do on lift truck equipment?
A: A castle nut is a slotted fastener with slots on top that align with a cotter pin or safety clip. The CR 60021-058 is used in Crown electric lift truck assemblies where positive locking is required to prevent fastener loosening during normal equipment operation. The castle design ensures the nut cannot rotate off under vibration.
Q: Will CR 60021-058 fit other lift truck brands besides Crown?
A: CR 60021-058 is a Crown OEM part. Verify thread size, pitch, and diameter match your equipment before ordering, as castle nuts are application-specific. Fitment depends on the specific assembly it fastens on your machine. Check your equipment manual or part diagram to confirm compatibility.
Q: How often should CR 60021-058 be inspected or replaced?
A: Castle nuts should be inspected during regular equipment maintenance to confirm the cotter pin or safety clip remains in place and the nut has not loosened. Replace CR 60021-058 if threads are stripped, damaged, or if the castle slots are deformed. Typical service life depends on equipment use and maintenance practices.
Q: What material is CR 60021-058 made from?
