When a worn-out spring brings your project to a halt, finding the right replacement fast is everything. Whether you're a hobbyist repairing a cabinet hinge, a maker building a custom mechanism, or a technician restocking your parts drawer, this torsion spring assortment gives you the sizes you need without hunting through multiple suppliers.
This kit includes steel torsion coil springs in two size profiles — 8.3×12.6mm and 0.5×6×2.5×18mm — available in silver (zinc-plated) and black (oxidized or coated) finishes. Wire diameter ranges typically from 0.5mm to 1.0mm depending on variant, with outer diameters of approximately 5.5mm–6mm. Pack sizes range from 20 to 500 pieces to suit both one-off repairs and bulk workshop stocking.
Typical use cases include DIY spring-loaded door latches and cabinet mechanisms, small appliance and electronics repair requiring torsion return springs, and prototype or maker projects needing compact coil springs for controlled rotational force.
Available in 8.3×12.6mm and 0.5×6×2.5×18mm configurations to cover a range of DIY and repair applications.
Silver zinc-plated for corrosion resistance; black finish for aesthetic or oxidation-treated applications. Choose the finish that suits your project.
Order from 20 to 500 pieces — ideal for single repairs, workshop restocking, or bulk maker projects without overpaying for quantity you don't need.
Made from steel wire with consistent coil winding for reliable torsional return force across repeated cycles in light-duty mechanisms.
Outer diameter of approximately 5.5mm–6mm makes these springs suitable for tight spaces in small appliances, hinges, and compact mechanical assemblies.
Designed to store and release rotational energy, providing consistent spring-back force for latches, levers, and hinged mechanisms.

Match the outer diameter and wire diameter to your existing spring or the space available in your mechanism. This assortment offers two size profiles — 8.3×12.6mm and 0.5×6×2.5×18mm — covering a range of compact DIY applications. If you're replacing a broken spring, measure the original's outer diameter, wire thickness, and leg length before selecting a variant.
The silver finish is zinc-plated, offering a degree of corrosion resistance suitable for indoor mechanisms and general DIY use. The black finish is oxidized or coated, which may suit aesthetic preferences or specific environmental conditions. Both are steel-core springs with equivalent mechanical function.
These springs are intended for light-duty indoor or sheltered applications. The silver zinc-plated variant offers basic corrosion resistance, but prolonged exposure to moisture or outdoor elements is not recommended. For outdoor use, consider applying a protective coating or selecting stainless steel springs.
These springs are suitable for cabinet hinges, door latches, small appliance return mechanisms, hobby robotics, prototype assemblies, and general DIY spring-loaded components. Always verify the outer diameter, wire gauge, and leg configuration match your specific application before installation.
For occasional repairs, the 20 or 50-piece packs are sufficient. If you run a workshop, repair bench, or maker space, the 100–500 piece packs offer better per-unit value and ensure you have spares on hand. Pack size can be selected from the variant options above.
These steel torsion springs are designed for consistent return force in light-duty applications with moderate cycle counts. For high-cycle industrial applications or heavy loads, a purpose-engineered spring with a specified cycle rating would be more appropriate. For typical DIY and hobby use, these springs perform reliably.
Wire diameter varies by size profile and is approximately 0.5mm for the smaller profile variant. Please refer to the variant options or contact us to confirm the exact wire diameter for your selected size before ordering.
