A torsion spring with a black finish for furniture fittings where the hardware is dark and a bright spring would stand out. The same coiling and leg forming as our nickel furniture springs, with the finish chosen to disappear into black hinges, brackets and frames.
Black plating keeps the spring visually quiet inside dark fittings, so the mechanism reads as one piece.
Wire diameter and coil count are set for doors, flaps and catches rather than for industrial loads.
Leg angle and length are matched to the fitting so no hand bending happens on the assembly line.
Fit with gloved hands or clean tooling. Black finishes show handling marks more readily than nickel, particularly on furniture hardware that is inspected at final assembly.

Springs supplied at a generic leg angle that assemblers have to adjust 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.

ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against the nickel plated furniture spring, this part is chosen purely on appearance. Nickel offers better wear and corrosion performance; black plating offers a finish that disappears.
Less than zinc or galvanising. It is chosen for appearance in dry indoor use. For damp positions we would recommend a different finish.
Matching is confirmed on samples against your own hardware, since black finishes vary noticeably between processes.
Geometrically yes, if the same drawing is used. Only the finish differs.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
