About Selecting Shock Absorbers
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)

Medium-Strength Steel Thin Hex Nuts—Grade 5
Also known as jam nuts, these 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. They're suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut. A zinc plating provides corrosion resistance in wet environments.

Low-Strength Steel Thin Hex Nuts
Also known as jam nuts, these 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. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels. Some of these screws meet ISO and DIN dimensional standards.
Nuts with fine and extra-fine thread spacing are less likely to loosen from vibration than nuts with coarse thread spacing.
