Pack of twelve extension springs

This pack supplies twelve Medline SP 9672 extension springs made from tempered spring steel with a nickel-plated finish. They suit a wide range of household, automotive, marine and workshop tasks where a reliable pull force is needed. The single-loop open ends allow quick attachment to fixed and moving parts.

Limits of the spring rate

Each spring has a 0.047 inch wire diameter, 3/8 inch outside diameter and 6-1/2 inch free length. Maximum safe load is 9.77 lbs and maximum deflection is 4.67 inches, so the spring cannot be stretched beyond that point without risk of permanent deformation. Designs requiring higher force or longer travel must use a different specification.

Corrosion resistance and mounting

The nickel plating protects the steel for indoor and outdoor use, resisting moisture in marine or appliance environments. Single-loop ends hook directly onto pins, bolts or brackets without special tools, making installation straightforward for maintenance and prototype work. Verify the line-art dimensions against your assembly before fitting.

Questions about this item

Should I buy the 12 pack or a smaller quantity for my project?

The 12 pack provides enough springs for multiple repairs or larger assemblies, reducing the need to reorder when working on several appliances, tools or mechanical devices.

What does the 9.77 lbs maximum safe load mean when I install these springs?

It means each spring can safely handle up to 9.77 lbs of pulling force before risking permanent deformation, so calculate your application's load to stay within that limit.

How does the single loop open end design affect installation?

The open loops let you hook the spring directly onto fixed and moving parts without special tools, making attachment quick on appliances, automotive parts, marine gear or toys.
