These nuts have excellent chemical resistance and can be used in saltwater environments. Also known as jam nuts, they are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place.
Black-oxide stainless steel nuts have a dark surface color.

Made with fine-pitch threads, vibration is less likely to loosen these metric nuts than those with coarse-pitch threads since the threads sit closer together. Fine and coarse threads are not compatible. Also called jam nuts, they are roughly half the height of standard hex nuts, so they’re good for applications with low clearance. However, they have less tensile strength than standard height nuts. Often used as locknuts, thread two against each other to further prevent loosening caused by vibration. You can also do this on a threaded rod, which creates a gripping point so you can turn it without damaging the threads. All are 18-8 stainless steel, which is almost as strong as steel but also won’t rust in outdoor, washdown, and other corrosive environments.
ISO 4035 nuts are functionally the same as DIN 439B nuts (sometimes also referred to as DIN 439-2), but have slightly different width tolerances. This ISO spec replaces the DIN spec, however DIN 439B is still a common reference point. These nuts have chamfered edges, so they’re less sharp than DIN 936 nuts.

These locknuts have good chemical resistance and may be mildly magnetic. Also known as Keps and K-Lock nuts, they have a free-spinning tooth lock washer that grips the material surface instead of threads for easy installation and mild vibration resistance. Height includes the thickness of the washer.
