A 3.0 mm wire torsion spring finished in nickel for furniture fittings, where the spring is often visible inside a hinge pocket or a drop-down flap. The nickel layer keeps it bright after years of being touched, and 3.0 mm wire gives enough torque for cabinet doors and lids without a bulky body.
3.0 mm wire sits in the range where a single compact body can close a cabinet door or hold a flap without a second spring.
Furniture springs are frequently seen when the door is open. Nickel stays bright where zinc would dull and stain.
Leg length and angle are set against your hinge or bracket rather than to a catalogue size, so no bending is needed on assembly.
Fit the spring over the hinge pin so that closing the door winds the coils tighter, not looser. Check that the shaft clears the inside diameter when the spring is fully loaded, because the body contracts as torque is applied.
Springs that dull or spot after a few years of handling in a visible fitting
Catalogue torsion springs whose leg angle never quite matches the fitting, forcing assembly workers to bend them by hand
Dimensional and load figures are set per order against your drawing or sample, so they are marked TBC rather than filled with catalogue numbers.

Compared with a zinc plated torsion spring of the same geometry, this part costs slightly more and looks considerably better after two years in a hand-operated fitting. Where the spring is hidden inside a closed mechanism, zinc plating is the more economical specification.
Yes. Body diameter and coil count set the torque, and the legs can be adjusted independently to suit your fitting.
Nickel is harder than zinc and holds up well to repeated contact, which is why it is the usual choice for visible furniture hardware.
Yes. Mirrored pairs are produced together so both sides of a fitting behave the same.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
