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.

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.

Brass Hex Panel Nuts
These panel nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. They can be fastened 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.
Nickel-plated brass panel nuts have excellent resistance to chemicals and salt water.

Ultra-Precision Lead Screws and Nuts
Operating with less backlash (play) than Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. All components are corrosion resistant for use in harsh environments. To ensure compatibility, select components that have the same thread type and thread size.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
