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.

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.

Ball Socket End Fittings with Safety Clip for Gas Springs
Thread these ball socket end fittings onto gas springs. They rotate in any direction on a ball stud to compensate for misalignment. Ball socket end fittings require a ball stud or ball stud mounting bracket (sold separately) to mount gas springs; they have a safety clip for secure attachment.
Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring. The fittings will increase your gas spring's extended and compressed lengths, so add the Length 1 value for each fitting you attach.
