Built from cold-rolled steel with a steel pin, this heavy-duty, nonswaged hinge is engineered for permanent installation by welding directly to metal surfaces. The nonremovable, tight-fit pin provides added security in demanding applications where hinge removal is not acceptable. At 0.408 pounds, it is a compact but sturdy component suited for gates, enclosures, access panels, and metal doors in commercial and industrial settings. Tradespeople working with metal fabrication or structural steel installations will find this hinge appropriate for a wide range of weld-on door and panel projects.\u003c\/p\u003e\u003cp\u003eThis hinge is intended for surface-mount weld applications on metal doors, frames, gates, utility enclosures, and access panels. It is appropriate for both new fabrication and retrofit work where a secure, nonremovable pivot point is required. The plain steel finish makes it well suited for environments where the hinge will be painted over or where bare steel is acceptable. It is sold individually and is compatible with applications requiring a 3-inch square hinge footprint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNonswaged design for direct surface application by welding to metal\u003c\/li\u003e\n\u003cli\u003eNonremovable pin for enhanced security in controlled-access applications\u003c\/li\u003e\n\u003cli\u003eTight pin fit reduces play and improves hinge stability\u003c\/li\u003e\n\u003cli\u003eCold-rolled steel construction with plain steel finish\u003c\/li\u003e\n\u003cli\u003e3-inch square profile for compact, heavy-duty pivot points\u003c\/li\u003e\n\u003cli\u003eCatalog model No. 560\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a weld-on surface-mount hinge for metal doors, gates, and enclosures requiring a 3-inch square hinge with a nonremovable pin.

Ensure all work surfaces and surrounding materials are clear of flammable materials before beginning any welding operation. The nonremovable pin means the hinge should be positioned and aligned correctly before final weld, as it cannot be disassembled after installation. Follow applicable local codes and safety standards for welding and metalwork.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3 inches square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cold-rolled steel body, steel pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Nonremovable, tight fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Style\u003c\/strong\u003e: Nonswaged, surface mount weld-on\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.408 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Model\u003c\/strong\u003e: 560\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N273904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51343090057522,"sku":"N273904","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550533.jpg?v=1782016290","url":"https:\/\/voomisupply.com\/products\/national-marker-n273904-weldable-door-hinge-3-inch-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
