Ultra-High-Load Fastener-Mount Compression Springs
For the heaviest loads, these springs have more than double the load capacity of High-Load Fastener-Mount Compression Springs. Secure by inserting a fastener through the hole at the base. Springs are a polyester/rubber blend that is wear, oil, and fuel resistant.
Energy is calculated in one of two ways. For an object that is dropped, energy equals the weight of the item multiplied by distance dropped. For an object moving horizontally, energy equals half of the mass of the item multiplied by velocity squared (1/2 mv²).

Extension Springs with Hook Ends
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch or mm of extension.

Corrosion-Resistant Extension Springs with Hook Ends
Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to extend than steel springs. As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch of extension or, for metric springs, millimeter of compression.
302 stainless steel springs have good corrosion resistance.
