It features a 0.18 inch outside diameter and a 1.25 inch free length, with a 0.022 inch wire diameter and closed and ground ends. The spring delivers a rated spring rate of 5 pounds per inch and handles a maximum work load of 4 pounds (17.79 N). Closed and ground end construction ensures flat, stable seating on both ends, which is critical for accurate load transfer in precision assemblies. The plain silver finish is the bare music wire surface with no added coating.\u003c\/p\u003e\n\u003cp\u003eThis spring is suited for use in light-duty precision mechanical assemblies across industrial, HVAC, plumbing, and electrical applications where a small-diameter, moderate-rate compression spring is required. Typical install scenarios include valve actuators, small relay mechanisms, control linkages, and instrument housings where consistent return force is needed. Its compact profile and tight dimensional tolerances make it appropriate for applications where space is constrained and load consistency matters. Sold in packs of 5 with a minimum order quantity of 1 pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.18 inch outside diameter suits tight-clearance bores and precision assemblies\u003c\/li\u003e\n  \u003cli\u003e5 lb\/in spring rate provides predictable, linear compression response\u003c\/li\u003e\n  \u003cli\u003e4 pound maximum work load rated; solid height of 0.446 inches prevents overcompression damage\u003c\/li\u003e\n  \u003cli\u003eClosed and ground ends ensure flat seating and stable load distribution\u003c\/li\u003e\n  \u003cli\u003eMusic wire construction meets AISI 302, ASTM A228, and ASTM A313 standards\u003c\/li\u003e\n  \u003cli\u003eRecommended hole diameter of 0.188 inches for guided installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision compression spring for general mechanical assemblies requiring a 0.18 inch OD, 1.25 inch free length, closed and ground end spring with a 5 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical or maintenance technicians as part of a subassembly or repair procedure. De-energize and depressurize any system before disassembling spring-loaded components. Use the specified 0.188 inch guide hole diameter when installing in a bore to maintain alignment and prevent buckling under load. Do not compress this spring beyond its solid height of 0.446 inches, as doing so will cause permanent set and alter the rated spring rate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Precision Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.022 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 5.0 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 4.0 pounds (17.79 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.446 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Hole Diameter\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Closed and Ground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Music Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 302, ASTM A228, ASTM A313\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161904\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 36257G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52092951560498,"sku":"36257G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e868ffe20e2313b732f7fe9843327b19.jpg?v=1790064221","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36257g-precision-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
