To select the best shock absorber for your application, you need to find the energy capacity your application requires. Use this formula to calculate the energy capacity required to stop a horizontal-moving load. For example, if you have a 250-lb. load moving at 25 inches per second, your calculation is (250 lbs. ÷ 772) × 252 = 202.4 in.-lbs. energy capacity.
Note: Choose a shock absorber with a higher energy capacity than you calculated. Factors such as driving force or an inclined surface will increase the energy capacity required.
Energy Capacity (in.-lbs.) = (Weight, lbs./772) × Velocity2 (in. per second)

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.
Zinc-plated steel nuts have an outer layer of zinc that protects the inner steel from rust and extends the life of the nut.
The distinctive coloring on blue-dyed steel nuts makes them easy to distinguish from inch-size nuts.
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 Although the DIN 936 and DIN 439B standards are no longer active, they are commonly referenced globally.

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 Although it’s no longer active, DIN 936 is still a commonly referenced standard for material and dimensional compatibility.
ISO 4035 nuts are functionally the same as DIN 439B nuts (sometimes called DIN 439-2), but have slightly different width tolerances. These nuts have chamfered edges that make them less sharp than DIN 936 nuts.

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 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.
DIN 936 nuts are sometimes slightly taller and wider than ISO 4035 nuts. While no longer active, DIN 936 is still a commonly referenced standard for material and dimensional compatibility.
ISO 4035 (formerly DIN 439B) nuts are chamfered, so their edges are less sharp than DIN 936 nuts. This new ISO standard is functionally the same as the DIN standard it replaced, with slightly different tolerances for width.

Made from brass, these metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. About half the height of standard hex nuts, they are useful in low-clearance applications but have less tensile strength. Also known as jam nuts, they help prevent loosening from vibration when tightened in pairs. Two nuts jammed together also function as a gripping point on a threaded rod, so you can turn the rod without damaging the threads.

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic. The head is knurled for slip-resistant controlled adjustment and the collar raises the head to make it easy to grip.

Made from 18-8 stainless steel, these thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments. They’re often called square jam nuts because they can be jammed together to hold each other in place. They’re easily gripped with a wrench due to their flat, broad sides, which also prevent them from rotating in channels and square holes. Compared to hex nuts, a greater area is in contact with the fastened surface. And compared to steel nuts, they’re slightly less strong.
These nuts meet DIN 562, an international standard that signifies their material and dimensions are compatible with other products and tools.
