Extension Springs with Special Ends

For specialty applications and connections, these springs have unique end types.

Extra-Stretch Extension Springs

These fabric-covered rubber springs stretch to up to three times their original length—much farther than traditional extension springs, tie downs, and shock cords.

Color-Coded Die Springs

Spring Steel

Lubricated 1080 Spring Steel Wire

Also known as music wire.

Lubricated 1065 Spring Steel Wire

This wire is coated with oil for corrosion resistance and lubricity. Use it for bundling and as tag wire.

Wear-Resistant 1095 Spring Steel Sheets and Strips

Also known as blue-tempered steel.

Easy-to-Form Wear-Resistant 1095 Spring Steel Sheets

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties.

1075 Spring Steel Strips

Also known as scaleless steel.

Easy-to-Form 1075 Spring Steel Sheets

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties.

Stress-Resistant 5160 Alloy Steel

5160 alloy steel handles repeated cycles of stress without breaking just like spring steel. It’s often used to make flat springs.

Easy-To-Form Multipurpose 1050 Spring Steel Sheets

Containing more carbon than low-carbon steel—but less than 1095 spring steel—1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use.
