✔️ 4.0 mm steel wire with 41 mm outer diameter and 120 to 500 mm lengths

This heavy duty tension extension spring delivers reliable pull force for industrial machinery frames, furniture hardware, and engine valve systems. Made from hardened 65Mn alloy, it handles continuous stress without permanent deformation. Pick up this corrosion resistant coil unit for elevator tracks, workshop tools, and mobile equipment that needs steady, repeatable torque.

✅ Precision ground 65Mn alloy steel core resists corrosion and wear ✅ Consistent 4.0 mm wire gauge supports heavy dynamic loading cycles ✅ Uniform 41 mm outer diameter fits standard mounting brackets securely ✅ Adjustable cut lengths span from 120 mm up to 500 mm for custom builds

💡 How do you size up an extension spring for a heavy duty rig without guessing?
- Line up the free length and solid height with your equipment mounts so the setup never binds when fully stretched out.
- Stick to the 4 millimeter wire spec because that thickness pulls through heavy loads without taking a permanent set down the road.
- Trust the 65Mn steel grade for handy upkeep jobs since it holds its bounce back through grease, heat, and constant vibration.
