When a worn or snapped torsion spring brings a hinge, latch, or small mechanism to a halt, finding the right replacement in the right angle and hand orientation can be a frustrating search. This range of 0.8mm wire diameter torsion springs is designed for engineers, technicians, and hands-on DIYers who need a reliable, dimensionally consistent clamp spring without ordering custom parts.
Each spring is wound from 0.8mm spring steel wire with outer diameters ranging from 4mm to 10mm (approximately 0.16 in to 0.39 in) and coil counts of 3, 6, or 9 turns. Available in left-hand and right-hand winding, and in four standard leg angles — 60°, 90°, 120°, and 180° — to match a wide variety of original equipment specifications.
Typical applications include cabinet door hinges, small appliance return mechanisms, clip-and-clamp assemblies, electronic enclosure latches, and precision instrument components where a compact torsion spring with a defined leg angle is required.
Outer diameters from 4mm to 10mm (0.16–0.39 in) with 3, 6, or 9 coil options — covering a broad spectrum of compact mechanism requirements.
Choose 60°, 90°, 120°, or 180° leg separation to match your original spring geometry and ensure correct return force direction.
Both left-spring and right-spring variants available, so you can replace either orientation without modification.
Wound from spring steel wire for consistent elastic return, resistance to set under repeated cycling, and durability in mechanical assemblies.
Small-diameter body suits tight installation spaces in hinges, clips, and enclosures where larger springs cannot fit.
Each listing is for one spring. Select your exact wire diameter × outer diameter × coil count, angle, and hand orientation from the variant options above.

Measure the outer diameter of your original spring with calipers. Then count the number of active coils (full 360° turns in the body, excluding the legs). Match both values to the variant options — OD and coil count together determine the spring rate and physical fit.
The winding direction determines which way the spring exerts torque. A left-hand (left spring) winds counter-clockwise when viewed from the leg end; a right-hand (right spring) winds clockwise. Using the wrong hand will cause the spring to unwind rather than store energy. Check your original spring or the mechanism's rotation direction before selecting.
The leg angle is the angle between the two straight legs of the spring when it is in its free (unloaded) state. Measure this on your original spring or refer to the equipment drawing. Common values are 90° for right-angle returns and 180° for straight-leg configurations. Selecting the wrong angle will result in incorrect preload or interference with surrounding parts.
Spring rate depends on wire diameter, outer diameter, coil count, and material. With a 0.8mm wire diameter, these are light-duty springs suited for small mechanisms such as hinges, latches, clips, and instrument components. They are not intended for heavy-load industrial applications. If you need specific torque values, contact us with your OD and coil count selection.
These springs are made from spring steel. Spring steel offers good mechanical properties but has limited corrosion resistance in wet or chemically aggressive environments without additional surface treatment. For outdoor or humid applications, consider applying a light protective coating after installation, or contact us to confirm finish options for your selected variant.
Spring steel can oxidize over time when exposed to moisture. For occasional outdoor use in sheltered locations, a light oil or protective spray after installation can extend service life. For continuous outdoor or marine exposure, a stainless steel spring would be more appropriate. Contact us if you need guidance on material selection for your specific environment.
Measure your original spring for: wire diameter (0.8mm), outer diameter (4–10mm range), coil count (3, 6, or 9), leg angle (60°/90°/120°/180°), and winding direction (left or right). All five parameters must match. If you are unsure of any measurement, contact us with photos or drawings of your original spring and we will help identify the correct variant.
