stainless steel tension spring designed for durable, reliable performance in commercial and DIY projects. Key benefits Long lasting construction: Made from stainless steel for strong wear resistance and protection against corrosion and rust. Smooth and safe finish: Burr surface reduces wear on mating parts and lowers the chance of damage during handling and installation. Consistent force and resilience: Uniform winding and strong end loops deliver steady pulling force and reliable rebound under repeated tension. Ready for heavy duty use: Thick hooks and secure loops at both ends provide firm attachment points for demanding applications. Specifications Material: Stainless steel Wire diameter: 0.9 mm (0.035 in) Outer diameter: 7 mm (0.28 in) Length: 314 mm (12.36 in) Ends: Loops/hooks at both ends for secure attachment Package includes: Stainless steel tension spring Performance and compatibility Functions as a tension or holding spring for mechanisms that require controlled pulling force and repeatable elastic response. Compatible with a wide range of equipment and assemblies used in manufacturing, research, automotive, aerospace, electronics, tools, toys, construction, and general machinery. Practical use scenarios Door and hatch : Use as a reliable spring on small access panels, hatches, or compartment doors where consistent pull and smooth operation are required. Mechanism restoration and : worn tension springs in hand tools, garden equipment, or mechanical assemblies to restore original function and tension. Hobby and model applications: Install in model kits, remote controlled vehicles, or prototype builds where precise, repeatable pulling force and compact size are needed. Notes Color in product images may vary slightly due to lighting and monitor differences. Allow a dimensional tolerance of 1 to 3 mm.
