A 5/8-inch nylon insert lock nut, commonly called a Nyloc nut, designed to resist loosening from vibration.
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 used in heavy-duty truck and trailer applications including suspension, wheel ends, and general assembly where a reusable, self-locking fastener is needed. The nylon insert creates a prevailing torque, holding the nut in place even under harsh operating conditions. Replace it if the nylon insert is worn, stripped, or the nut no longer holds its locking torque.
