Built from chromium alloy steel with a trapezoidal wire cross-section, it delivers a spring rate of 101 pounds per inch and a maximum deflection load of 144 pounds at full compression. The 3-inch free length, 3\/4-inch hole diameter, and 3\/8-inch rod diameter make it a direct fit for standard die sets requiring a blue-coded medium-duty spring. This part is typically installed by toolmakers, die setters, and maintenance machinists.\u003c\/p\u003e\u003cp\u003eThis die spring is suited for industrial tooling environments including metal stamping, forming, and injection mold applications. The blue color coding follows ISO 10243 duty-rating conventions, identifying this spring as a medium-duty unit. It is appropriate for applications demanding up to 1.5 inches of maximum deflection and a sustained load capacity of 144 pounds, making it a practical choice for moderate-force compression tooling setups in both production and maintenance-repair contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChromium alloy steel construction for durability under repeated compression cycles\u003c\/li\u003e\n\u003cli\u003eTrapezoidal wire cross-section provides higher load capacity relative to round wire at equivalent size\u003c\/li\u003e\n\u003cli\u003e101 lb\/inch spring rate with 144-pound maximum deflection load\u003c\/li\u003e\n\u003cli\u003e1.5-inch maximum deflection at full compression\u003c\/li\u003e\n\u003cli\u003eBlue color coding indicates medium-duty rating per ISO 10243 convention\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 and ISO\/TS 16949:2009 certified quality systems; TUV Rheinland registered\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard die spring for tooling applications requiring a 3\/4-inch hole diameter, 3\/8-inch rod diameter, and 3-inch free length in a medium-duty blue-coded spring specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie spring installation and replacement should be performed by qualified toolmakers or die maintenance personnel with the press fully de-energized, locked out, and tagged out per OSHA lockout\/tagout requirements. Inspect the mating die pocket and guide rod for wear or damage before seating the new spring. Do not compress the spring beyond its rated maximum deflection of 1.5 inches, as over-compression will reduce service life and may cause premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 144 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 101 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty Rating\u003c\/strong\u003e: Medium-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Blue\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\u003eWeight\u003c\/strong\u003e: 0.125 pounds\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161905\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 103-412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52023914299698,"sku":"103-412","price":18.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd6ad6a03d44fc954ae088b3b049cca.jpg?v=1790014376","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-412-die-spring-blue-medium-duty","provider":"Voomi Supply","version":"1.0","type":"link"}
