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.
Zinc-plated springs have mild corrosion resistance.
