Compression Springs
As you squeeze a compression spring, it pushes back to return to its original length. Spring rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the spring rate, the harder it is to compress the spring.
Springs with closed and ground ends sit flat, so they won’t buckle.

Corrosion-Resistant Compression Springs
These springs are more corrosion resistant than standard compression springs. They're also easier to compress than standard compression springs. As you squeeze a compression spring, it pushes back to return to its original length. Spring rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the spring rate, the harder it is to compress the spring.
302 stainless steel springs have good corrosion resistance.

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).
