thin Heavy Profile Hex Nut

These rust-resistant nuts are ideal for outdoor and damp settings. 

These nuts, which are rated Class 12 or Grade 9, are around 20% stronger than high-strength steel nuts. They are robust enough to hold parts of large equipment like excavators and bulldozers in place. Make sure your screw has a similar strength rating to prevent stripped threads during installation. 

These nuts are almost half as strong as medium-strength nuts and are rated Grade 2, Class 6, or lower. They work well for light-duty fastening tasks like locking access panels. In order to prevent thread stripping during installation, use them with screws that have a comparable strength grade. 

Brass—Conductive and nonmagnetic, brass nuts are frequently used to fasten electrical components inside enclosures, including mounting brackets and circuit board assemblies. They won't harm other fastening elements because they are softer than most metals.
