Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels. Also known as jam nuts, they can be threaded together to form a locknut that won’t move or loosen due to vibration. When fastening threaded rod, you can use two nuts to create a point for tightening the rod with a wrench. These nuts have less tensile strength than a standard hex nut when used alone.
Steel nuts are best for dry environments, since exposure to moisture and chemicals will cause them to rust.
Nuts that meet DIN 936 and ISO 4035 (formerly DIN 439B) adhere to international standards for dimensions and material composition to ensure compatibility with other products and tools. Although the DIN 936 and DIN 439B standards are no longer active, they are commonly referenced globally.

These nuts are half the height of standard hex nuts, and have closely spaced threads to prevent loosening from vibration. They are not compatible with coarse threads. Half as strong as medium-strength steel nuts, they are often used for light-duty applications, such as fastening signs in place.
Also known as jam nuts, they can be used in place of standard nuts when height clearances are tight, or threaded together to form a locknut. When fastening threaded rod, you can use two nuts to create a point for tightening the rod into place with a wrench. These nuts have less tensile strength than a standard hex nut when used alone.

Zinc-plated steel nuts have an outer layer of zinc that protects the inner steel from rust and extends the life of the nut.

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. Commonly used as locknuts, threading a thin nut against any other hex nut prevents loosening caused by vibration. You can also use them as jam nuts by threading two of these thin nuts against each other on a threaded rod to create a gripping point for turning the rod without damaging its threads. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.
DIN 936 nuts are sometimes taller and wider than ISO 4035 nuts. Although it’s no longer active, DIN 936 is still a commonly referenced standard for material and dimensional compatibility.

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.
DIN 936 nuts are sometimes slightly taller and wider than DIN 439B nuts. Although it’s no longer active, DIN 936 remains a commonly referenced standard for material and dimensional compatibility.

These metric nuts are made of 316 stainless steel and half as tall as regular hex nuts—use them around chemicals and salt water when space is limited. Also known as jam nuts, they can be tightened in pairs to prevent loosening from vibration. Jamming two of these nuts together can also create a gripping point on a threaded rod, letting you use a wrench to turn the rod without damaging the threads.
