Built from chromium-vanadium steel, it features a D-shaped wire cross-section and a yellow color coding that identifies its extra heavy-duty rating at a glance. The spring has a 3\/4-inch hole diameter, a 3\/8-inch rod diameter, and a 4-inch free length, allowing it to deliver controlled, consistent force throughout its stroke. This part is installed by toolmakers, die setters, and machine maintenance technicians working in manufacturing and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThis die spring is suited for high-load stamping and forming applications where consistent spring pressure is critical to die performance. The 4-inch free length and 1-inch maximum operating deflection make it appropriate for moderate-stroke tooling setups. Its extra heavy-duty rating places it at the high end of standard die spring classifications, commonly used where lighter springs would fatigue prematurely under repetitive cycling. The yellow color coding follows the ISO 10243 international standard for die spring classification, making it straightforward to identify and replace in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra heavy-duty rating with a maximum deflection load of 374 pounds\u003c\/li\u003e\n  \u003cli\u003eChromium-vanadium steel construction for fatigue resistance under cyclic loading\u003c\/li\u003e\n  \u003cli\u003eD-shaped wire cross-section for increased load capacity relative to round wire\u003c\/li\u003e\n  \u003cli\u003eYellow color coding per ISO 10243 for quick duty-rating identification\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 10243, ISO 9001:2015, and NAAMS standards\u003c\/li\u003e\n  \u003cli\u003eMaximum operating deflection of 25 percent of free length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ISO 10243-compliant replacement die spring for extra heavy-duty tooling applications requiring a 3\/4-inch hole diameter, 3\/8-inch rod diameter, and 4-inch free length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDie springs are installed and replaced by toolmakers or die maintenance technicians. Always power down and lock out the press before accessing the die set. The spring must be seated squarely on the rod with no lateral loading that could cause buckling. Do not compress the spring beyond the rated maximum operating deflection to avoid permanent set or premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 374 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Deflection\u003c\/strong\u003e: 25 percent of free length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTravel To Solid Load\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Shape\u003c\/strong\u003e: D-Shaped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Extra Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Chromium-Vanadium Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.194 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: 9-1216-36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DAYTON LAMINA","offers":[{"title":"Default Title","offer_id":52094096900402,"sku":"9-1216-36","price":18.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76204193f4600cab92ecf7625dbb3410.jpg?v=1790065057","url":"https:\/\/voomisupply.com\/products\/dayton-lamina-9-1216-36-die-spring-374-lb-extra-heavy-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
