Steel Hex Panel Nuts
Fasten these panel nuts with a wrench for more torque while tightening than knurled panel nuts. Also known as dress nuts, they're extremely thin for use in tight spaces such as electrical panels.
Zinc-plated steel nuts resist corrosion in wet environments.
Black-oxide steel nuts have a dark surface color.
