Good to know
- Use with A563 DH 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.
- A larger, thicker pattern than a finished hex nut — more bearing surface for larger diameters and higher loads.
- Zinc-plated for general indoor and light-outdoor corrosion resistance.
