It features a trapezoidal wire profile wound from chromium alloy steel, which delivers a higher load capacity per unit of length compared to round-wire springs. The spring accepts a 0.75-inch hole diameter and a 0.375-inch rod diameter, with a free length of 1.25 inches. At full compression, it handles a maximum deflection load of 160 pounds across a maximum deflection of 0.63 inches, giving a rated spring rate of 256 pounds per inch. The blue color coding indicates medium-duty classification per standard die spring conventions.\u003c\/p\u003e\u003cp\u003eThis spring is suited for light-to-medium force requirements in metal stamping, die forming, and precision tooling setups found in manufacturing and fabrication environments. It is installed by tool and die makers, machine maintenance technicians, and industrial MRO professionals. The compact 1.25-inch free length makes it appropriate for applications where space in the die set is limited and a controlled, repeatable spring force is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTrapezoidal wire cross-section for higher load density versus round-wire die springs\u003c\/li\u003e\n\u003cli\u003eChromium alloy steel construction for durability under cyclic compression loads\u003c\/li\u003e\n\u003cli\u003e160-pound maximum deflection load with 0.63-inch maximum deflection\u003c\/li\u003e\n\u003cli\u003eSpring rate of 256 pounds per inch for predictable, linear force output\u003c\/li\u003e\n\u003cli\u003eBlue color coding identifies medium-duty rating at a glance\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\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit die spring for medium-duty stamping die sets requiring a 0.75-inch hole diameter, 0.375-inch rod diameter, and 1.25-inch free length in standard die spring bores.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDie spring replacement and die set servicing should be performed by qualified tool and die technicians with the press fully de-energized, ram locked out, and all stored energy released per OSHA lockout\/tagout procedures. Inspect the spring seat, guide rod, and bore for wear or damage before installing a replacement spring. Do not exceed the rated maximum deflection of 0.63 inches during operation, as over-compression accelerates fatigue 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection Load\u003c\/strong\u003e: 160 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deflection\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 256 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\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 Code\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: 103-405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASSOCIATED SPRING","offers":[{"title":"Default Title","offer_id":52038953435442,"sku":"103-405","price":15.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4ebaf6f1dd350394ebdb6181f380d91.jpg?v=1790025822","url":"https:\/\/voomisupply.com\/products\/associated-spring-raymond-103-405-die-spring-blue","provider":"Voomi Supply","version":"1.0","type":"link"}
