Overview

A hub nut with the wrong thread pitch or shaft diameter won't torque down properly, and a loose wheel on the balancer shaft means every reading you take is suspect. The Coats 8112103 is the OEM hub nut built for 40mm Coats balancer shafts with standard 8mm thread spacing. The threading matches exactly, so it seats clean and stays secure through every job.

High-grade steel construction means it's not going to strip or deform with regular use in a busy shop. This is a genuine Coats replacement part, so you're getting the same fit and material spec as the original, not a close approximation. Aftermarket hub nuts with slightly off threading are a common headache. They seem fine at first, then they stop holding under load, and suddenly you've got a vibration problem sitting on top of a hardware problem. The 8112103 eliminates that risk entirely. One correct part, correct fit, correct readings every time. If you're also sourcing other balancer consumables, it's worth checking compatible pressure cups and cone sets at the same time to keep your machine fully dialed in. We stock genuine Coats OEM replacement parts and ship fast, so you're not burning time waiting on a small but critical component.
