It features a 90-degree deflection angle, a coil outside diameter of 0.309 inches, and a wire diameter of 0.040 inches. With 4.25 coils and a left-hand wind direction, this spring delivers controlled torque at a rated 1.473 in\/lb at leg length. The rod size is 0.187 inches and the maximum tool size is 0.187 inches. This part is typically installed by mechanical assemblers, maintenance technicians, and OEM equipment builders working with precision spring-loaded mechanisms.\u003c\/p\u003e\u003cp\u003eThis torsion spring is suited for light-duty mechanical assemblies requiring a compact, accurately wound spring with a defined deflection angle. With a leg length of 1.250 inches and a left-hand wind, it fits applications where rotational return force must be repeatable and consistent. Typical use cases include small appliance mechanisms, HVAC damper linkages, control levers, and similar assemblies where a 90-degree torsion element is required. The package quantity is 6 units per package with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree deflection angle for defined rotational return force\u003c\/li\u003e\n\u003cli\u003eLeft-hand wind direction for correct torque orientation in mating assemblies\u003c\/li\u003e\n\u003cli\u003e0.309 inches coil outside diameter with 0.040 inches wire diameter for compact fitment\u003c\/li\u003e\n\u003cli\u003e1.473 in\/lb torque at leg length for predictable spring performance\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in mechanical environments\u003c\/li\u003e\n\u003cli\u003eRod size and maximum tool size of 0.187 inches for straightforward installation tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit torsion spring for mechanical assemblies requiring a left-hand wound spring with a 0.309 inches outside diameter and 90-degree deflection angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTorsion springs should be installed by qualified mechanical technicians familiar with spring-loaded assemblies. Always de-energize and lock out any powered equipment before servicing spring mechanisms. Use appropriate spring installation tools sized to the 0.187 inches maximum tool size to avoid distorting coils during installation. Verify wind direction matches the assembly requirement before installation, as substituting an opposite-hand spring can result in improper function.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeflection Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirection of Wind\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Outside Diameter\u003c\/strong\u003e: 0.309 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Coils\u003c\/strong\u003e: 4.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeg Length\u003c\/strong\u003e: 1.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Size\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Tool Size\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque at Leg Length\u003c\/strong\u003e: 1.473 in\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GT4018709-ML\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51972178673970,"sku":"GT4018709-ML","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfbec34a2a500a97d5f92a24937747e0.jpg?v=1789963785","url":"https:\/\/voomisupply.com\/products\/gardner-spring-gt4018709-ml-torsion-spring-90-deg-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
