Good to know
- Use with Grade 5 bolts/studs — match or exceed the bolt grade so the nut is never the weak link.
- Fine (UNF) thread — higher tensile strength and better resistance to loosening than coarse.
- A thin nut — used to lock a primary nut (double-nut method) or set and hold a position on threaded rod.
- Plain finish has no corrosion coating — oil, wax, or paint for outdoor or wet service, or ask us about a plated option.
