Extension, Compression, and
Torsion Spring Assortments

Keep a collection of three of the most common types of springs on hand.

Compression Spring Assortments

When compression springs are pushed together, they push back to return to their original length. Commonly used in shock absorbers and to secure batteries, they're are easier to push together than die springs.

Extension and Compression Spring Assortments

These assortments include springs that pull and springs that push.

Extension Spring Assortments

The more you extend these springs, the greater the force the springs will exert to pull the two points back together. They're commonly used to tension cable, return an air cylinder to its starting point, and hold a door closed.
