Greenlee Fairmont NR1 Nut Runner with Adapter

Using the Greenlee NR1 Nut Runner is easy. First, choose the right opening on the nut runner for the square nut size you're working with. The 7/16' hex quick - change adapter can be used when needed. If you have a bolt with extra length, up to 6' (152 mm), the deep well design can handle it. When storing, take advantage of its slim profile. Just make sure to keep it in a dry place. As for maintenance, after each use, clean the nut runner and adapter. Check the openings for any debris or damage. If you notice any issues, don't use it until it's fixed.
