Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is typically used with a shackle bolt to secure trailer leaf spring suspension components. The lock nut resists loosening from vibration, ensuring the shackle connection stays tight. Replace it when the threads are damaged or the locking feature (such as a nylon insert or deformed thread) wears out.
