NUT - CASTELLATED (Yale YT21234200)

A damaged castellated nut can compromise the security of a pinned joint, leading to loosening under vibration. During inspection, a castellated nut may show wear on its slots or threads, indicating the need for replacement. This aftermarket replacement part references the Yale catalog number YT21234200. The nut type uses slots to accept a cotter pin, providing a positive locking mechanism. A common failure consequence is the loss of preload in a bolted assembly, which can cause component separation. Keeping a castellated nut in sound condition helps maintain the integrity of critical connections. Verify the serial number or application, then call (562) 693-7748.
