Need some heavy-duty extension springs for your project?

This 4-pack of dual hook tension springs has you covered!

Each spring measures 10 inches long with 1-1/4 inch outer diameter, made from nickel-plated spring steel that's seriously tough.

The 0.14 inch wire diameter provides plenty of strength while maintaining good flexibility.

These springs are wear-resistant, heat-resistant, and corrosion-resistant - they won't deform or fail even with long-term use.
The dual hook design makes installation easy - just attach to eyelets or other connection points.

Perfect for machinery construction, industrial equipment, furniture mechanisms, gates, screen doors, or any application where you need reliable tension.
The nickel plating adds extra protection against rust and corrosion.
These aren't flimsy hardware store springs - they've got professional quality that can handle real work.
Use them in production assembly, experiments, R&D projects, or maintenance repairs around your shop or home.

The package includes 4 identical springs so you have spares or can use multiple in your project.
The elasticity controls machine movement, absorbs impact and vibration, or measures force - super versatile for countless applications.

Just be aware there might be a slight size variation of ±3mm due to manual measurement.
Quality springs that won't let you down when you need dependable tension performance!
