Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 240 pounds per inch and a maximum deflection load of 126 pounds at 0.53 inches of travel. The gold color coding identifies this spring as a heavy-duty unit per standard die spring classification. It is installed by tool and die makers, machine builders, and maintenance technicians working on press tooling and industrial fixtures.\u003c\/p\u003e\n\u003cp\u003eThe 105-307 fits applications requiring a 0.625-inch hole diameter and an 11\/32-inch rod diameter, with a free length of 1.75 inches. This spring is suited for use in progressive dies, compound dies, stripping operations, and other precision tooling where controlled load deflection is critical. Its chromium alloy steel construction handles the high-cycle fatigue demands common in production stamping environments. Manufactured under ISO 9001:2008 and ISO\/TS 16949:2009 quality management systems, it meets the dimensional and performance standards expected in industrial tooling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTrapezoidal wire cross-section increases load capacity and fatigue life compared to round wire die springs\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 240 pounds per inch provides predictable, consistent force output\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection load of 126 pounds at 0.53 inches of travel\u003c\/li\u003e\n  \u003cli\u003eGold color coding identifies heavy-duty duty rating per standard die spring classification\u003c\/li\u003e\n  \u003cli\u003eChromium alloy steel construction for high-cycle durability in production tooling\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard heavy-duty die spring for tooling fixtures, stamping dies, and punch press applications requiring a 0.625-inch hole diameter, an 11\/32-inch rod diameter, and a 1.75-inch free length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs should be installed by qualified tool and die technicians or maintenance personnel familiar with press tooling. Always de-energize and lock out the press before replacing springs in a die assembly. Ensure the rod diameter and hole diameter clearances match the spring specifications before installation to prevent buckling or binding during operation. Do not compress the spring beyond its rated maximum deflection, as over-compression significantly reduces fatigue life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.344 inches (11\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 126 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 240 pounds per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: Trapezoidal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANAB Accredited, ISO 9001:2008 Certified, ISO\/TS 16949:2009 Certified, TUV Rheinland Registered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: ASSOCIATED SPRING RAYMOND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 105-307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52027559674162,"sku":"105-307","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d820dafeb044b075e9d7ebce31e301d6.jpg?v=1790017182","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-105-307-die-spring-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
