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

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. Rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the rate, the harder it is to compress the spring.
302 stainless steel springs have good corrosion resistance.

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. Rate is the amount of force required for every inch of compression. The higher the rate, the harder it is to compress the spring.

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. Rate is the amount of force required for every inch of extension.
