High-Load Fastener-Mount Compression Springs
These springs handle higher loads than standard 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).

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).

Fastener-Mount Compression Springs
Mount these springs on their side to absorb impact in a small amount of space. Differently sized screw holes on either side allow for mounting flexibility. Springs are a polyester/rubber blend that is wear, oil, and fuel resistant.
Energy is calculated based on the direction of your load. 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).

Flanged Compression Springs
Flanges on the ends of these springs provide a flat mounting surface. Springs are a polyester/rubber blend that is wear, oil, and fuel resistant.
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. The higher the spring rate, the harder it is to compress the spring.
