Good to know
- Use with Grade 5 bolts/studs — match or exceed the bolt grade so the nut is never the weak link.
- Coarse (UNC) thread — faster to install and more tolerant of nicks and corrosion.
- The standard six-sided nut for general bolting; size the wrench to the width across flats shown above.
- Zinc-plated for general indoor and light-outdoor corrosion resistance.
