Compression Springs

Use these springs in noncorrosive environments.

Corrosion-Resistant Compression Springs

These springs are more corrosion resistant than standard compression springs.

Compression Spring Stock

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Compression Spring Stock

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Precision Compression Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Precision Compression Springs

Made of stainless steel, these springs are more corrosion resistant than steel compression springs.

Mil. Spec. Compression Springs

These springs meet MS24585 and come with a traceable lot number and material test report.

Plastic Compression Springs

A lightweight, nonmagnetic, and nonconductive alternative to metal springs, these plastic springs are better for corrosive environments and applications where metal springs cannot be used, such as in sensitive imaging equipment and machines where stray electrical current may cause damage.

Made-to-Order Compression Springs

If you're designing something unique or can't find the exact size spring you need, we'll get it for you.

Confined-Space Conical Compression Springs

Install these springs in tight spots. When pushed together, the coils nest within each other.

Ultra-High-Load Fastener-Mount Compression Springs

For the heaviest loads, these springs have more than double the load capacity of High-Load Fastener-Mount Compression Springs. Secure by inserting a fastener through the hole at the base.

High-Load Fastener-Mount Compression Springs

These springs handle higher loads than standard fastener-mount compression springs. Secure by inserting a fastener through the hole at the base.

Fastener-Mount Compression Springs

Differently sized mounting holes on either side allow for mounting flexibility.

Flanged Compression Springs

Flanges on the ends of these springs provide a flat mounting surface.

Torsion Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Torsion Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs.

Made-to-Order Torsion Springs

Whatever the size, we'll get the spring you need.

Garter Springs

With ends that are connected to form a circle, these garter springs exert strong radial (towards the center) forces from all directions to maintain pressure on shafts or in seals.

Extension Springs

Extension Springs with Loop Ends

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Extension Springs with Loop Ends

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Mil. Spec. Extension Springs with Loop Ends

These steel springs meet MS 24586 and come with a traceable lot number and material test report.

Corrosion-Resistant Extension Springs with Hook Ends

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Extension Springs with Hook Ends

Use these steel springs in noncorrosive environments.

Extension Springs with Special Ends

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

Extension Spring Stock

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Extension Spring Stock

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Made-to-Order Extension Springs

Whatever the size, we'll get the spring you need.

Overload-Prevention Extension Springs

These zinc-plated steel springs have mild corrosion resistance.

Swiveling Extension Spring Stud Anchors

A black-oxide finish provides mild corrosion resistance.

Corrosion-Resistant Extension Spring Stud Anchors

These stainless steel anchor studs offer excellent corrosion resistance.

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.

Corrosion-Resistant
Overload-Prevention Extension Springs

Made of stainless steel, these springs are more corrosion resistant than steel extension springs.

Extension Spring Stud Anchors

A black-oxide finish provides mild corrosion resistance.

Corrosion-Resistant Swiveling
Extension Spring Stud Anchors

These stainless steel anchor studs offer excellent corrosion resistance.

Strip Springs

Constant-Force Springs

No matter how far you extend them, these springs pull back with the same amount of force.

Variable-Force Springs

Unlike constant-force springs, the farther you pull these, the harder they are to pull. Use them for applications where the load becomes lighter as the spring contracts, such as in automated dispensing machines.

Clip-On Constant-Force Springs

Clip the end onto a flat surface to install—no fasteners needed. Once installed, these springs pull back with the same amount of force no matter how far you extend them.

Die Springs

Metric Color-Coded Die Springs

Colors and sizes follow ISO 10243 for metric die springs.

Color-Coded Die Springs

These springs follow the Raymond die spring color code.

Die Spring Stock

Keep these 36" springs on hand so you can cut the right length whenever you need it.

Die Springs

Use these spring-tempered steel die springs for low-cycle applications such as trimming and stamping.

Die Spring Screw Caps

In addition to providing a backing for springs, these screw caps can also be used to control spring tension.

Die Spring Cages

Protect dies from damage caused by spring failure. Cages enclose springs to retain fragments if they break.

Corrosion-Resistant Die Springs

A quieter, more vibration-resistant alternative to traditional steel die springs, these polyurethane springs resist oxidation, oil, and abrasion in high-load, high-pressure applications.

Rotor Springs

Wind these springs to store power, then release them to create rotary motion—similar to winding a wristwatch. Also known as clock springs and power springs.
