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.
- Reverse (left-hand) thread — tightens counterclockwise; fits only left-hand bolts and rod.
- Plain finish has no corrosion coating — oil, wax, or paint for outdoor or wet service, or ask us about a plated option.
