1 1/4" Springs | McMaster-Carr

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.

Confined-Space Conical Compression Springs

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

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.

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.

Extension Springs with Hook Ends

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Extension Springs with Hook Ends

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 Extension Spring Stud Anchors

These stainless steel anchor studs offer excellent corrosion resistance.

Swiveling Extension Spring Stud Anchors

A black-oxide finish provides mild corrosion resistance.

Die Springs

Color-Coded Die Springs

These springs follow the Raymond die spring color code.

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.

Spring Pins

Slotted Spring Pins

Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes.

Coiled Spring Pins

These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round.

Heavy Duty Coiled Spring Pins

For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round.
