Adjustment nut
Good solid product but could be made out of steel to last longer. 6 crews run our grinders 3 days a week and the next time I have to replace one I will make it out of steel. Magna-Matic Response: The reason we make this part out of plastic is the plastic will wear and not seize. If the part were steel when grit got into the threads it would seize and prevent any adjustment. As a plastic part it will take quite some time before it wears enough to no longer adjust and then the threaded rod will not take any damage. This part is designed to wear.
