Coats 8101039 1/2" Nylon Insert Lock Nut, GR4

Tire changers run hard, and the vibration they generate during normal operation is constant. Over time, that vibration works on fasteners. Standard nuts back out. Hardware loosens. The Coats 8101039 is a 1/2-inch nylon insert lock nut built specifically to handle that. The nylon insert grips the bolt threads and resists loosening under vibration, so the fastener stays where you put it.

This is a genuine OEM-quality replacement part for Coats tire changers, rated GR4 and constructed from steel with a nylon insert. Part number 8101039 is the correct reference if you're cross-referencing your machine's parts diagram. It's a straightforward swap, and using the right part keeps your machine operating the way it was designed to. No substituting hardware store generics on equipment you depend on to turn cars around.

We carry genuine Coats replacement parts and ship them fast. Whether your machine is already down or you're building out a repair kit before the problem shows up, having the correct hardware on the shelf means less downtime when it counts. This is the part to have on hand.
