Stainless Steel Hex Panel Nuts
All of these stainless steel panel nuts have some chemical resistance. They can be fastened with a wrench for more torque while tightening than knurled panel nuts. Also known as dress nuts, they are extremely thin for use in tight spaces such as electrical panels.
18-8 stainless steel nuts have good chemical resistance. They may be mildly magnetic. Those with a black-oxide finish have a dark surface color.
316 stainless steel nuts have excellent chemical resistance and can be used in saltwater environments.
