This heavy-duty hinge features a nonswaged body and a nonremovable, tight-fit pin, making it well suited for secure, permanent installations. Fabricated from cold-rolled steel with a plain steel finish, it is intended for welded application rather than screw or bolt mounting. Metalworkers, millwrights, and maintenance technicians typically specify this hinge when a flush-mount, weld-on solution is required for metal enclosures, gates, or access panels.\u003c\/p\u003e\u003cp\u003eThe N273888 is used in light industrial and commercial applications where a durable, weld-on hinge is preferred over surface-fastened hardware. Its nonswaged design allows full surface contact with the mounting substrate, which is critical for strong weld adhesion. The tight, nonremovable pin provides added security in applications where hinge tamper-resistance or pin retention matters, such as utility enclosures, equipment access doors, and fabricated metal assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNonswaged body enables full surface contact for reliable weld-on installation\u003c\/li\u003e\n\u003cli\u003eNonremovable pin adds security and prevents accidental disassembly\u003c\/li\u003e\n\u003cli\u003eTight-fit pin construction for more secure, stable hinge action\u003c\/li\u003e\n\u003cli\u003eCold-rolled steel hinge body and steel pin for consistent material properties\u003c\/li\u003e\n\u003cli\u003ePlain steel finish suitable for painting or coating after installation\u003c\/li\u003e\n\u003cli\u003eCompact 2-inch square profile fits tight-clearance door and panel applications\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, enclosures, and fabricated panels requiring a nonremovable-pin, nonswaged hinge solution.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified welders or metalworkers using appropriate MIG, TIG, or stick welding equipment. Ensure the mounting surface is clean, free of coatings, and properly fixtured before tacking the hinge in place. Verify door alignment before completing full weld passes to avoid binding. Allow welds to cool fully before cycling the hinge or applying finish coatings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 2 inches square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Nonremovable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Style\u003c\/strong\u003e: Nonswaged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Method\u003c\/strong\u003e: Weld-on surface application\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHinge Material\u003c\/strong\u003e: Cold-rolled steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.175 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\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: N273888\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL MARKER","offers":[{"title":"Default Title","offer_id":51347707003186,"sku":"N273888","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550530.jpg?v=1782111660","url":"https:\/\/voomisupply.com\/products\/national-marker-n273888-weldable-door-hinge-2-in-square","provider":"Voomi Supply","version":"1.0","type":"link"}
