Built from chromium-vanadium steel with a D-shaped wire profile, it delivers a maximum deflection load of 36 pounds at 0.37 inches of travel. The free length is 1 inch, the hole diameter is 3\/8 inch, and the rod diameter is 3\/16 inch. This spring meets ISO 10243 international standards and is color-coded blue to identify its medium-duty load class at a glance. Licensed toolmakers and die maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for precision tooling applications in stamping, injection molding, and progressive die operations. It is commonly installed in commercial and industrial press tooling where controlled deflection and repeatable load characteristics are required. The ISO 9001:2015 registration and NAAMS compliance make it a fit for automotive supplier tooling environments where dimensional and quality standards are strictly enforced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChromium-vanadium steel construction for fatigue resistance under cyclic loading\u003c\/li\u003e\n  \u003cli\u003eD-shaped wire cross-section for higher load capacity relative to round-wire springs of the same envelope\u003c\/li\u003e\n  \u003cli\u003eBlue color coding identifies medium-duty load class per ISO 10243\u003c\/li\u003e\n  \u003cli\u003eMaximum deflection load of 36 pounds at 0.37 inches travel\u003c\/li\u003e\n  \u003cli\u003eTravel to solid of 0.46 inches provides a defined compression limit\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 10243, ISO 9001:2015, and NAAMS standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ISO 10243-compliant medium-duty die spring for use in stamping dies, molds, and tooling fixtures requiring a 3\/8 inch hole diameter and 3\/16 inch rod diameter with a 1 inch free length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs are installed by toolmakers and die maintenance technicians with the press or machine de-energized and all stored energy released before service. The spring must be seated squarely on the rod or in the pocket to prevent side loading, which accelerates fatigue failure. Do not compress beyond the rated travel-to-solid dimension during setup. Inspect for cracking or set at each die service interval and replace springs in matched sets when possible.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Deflection\u003c\/strong\u003e: 37.50 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTravel To Solid\u003c\/strong\u003e: 0.46 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: D-Shaped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium-Vanadium Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.007 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 10243, ISO 9001:2015, NAAMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161905\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: DAYTON LAMINA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9-0604-21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":51972181557554,"sku":"9-0604-21","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09f8ef5aeaa0ec1ff83c392ff2eddd1f.jpg?v=1789963848","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-9-0604-21-die-spring-1-in-blue-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
