National Hardware N273-888 Weld-on Plain Steel Hinge 2x2

Product Description

The NATIONAL HARDWARE N273-888 is a cold-rolled steel weld-on hinge designed for surface mounting on metal fabrications and structural assemblies. The hinge measures 2 x 2 inches and features a nonswaged, heavy-duty construction with a fixed, nonremovable steel pin. The tight pin fit increases security and reduces play in high-stress applications. This hinge is intended for welded installation directly onto metal surfaces and carries a plain steel finish with no plating or coating. Metal fabricators, ironworkers, and welding contractors are the primary installers of this component.

The N273-888 is suited for light industrial and commercial metal fabrication where a welded surface hinge is required. Typical applications include metal gate construction, enclosure panels, equipment doors, and structural access covers. The nonswaged barrel profile allows full surface contact with the weld base material, making it appropriate for flat-plate and tube steel assemblies. The plain steel finish is compatible with field painting or powder coating after installation.

Key Features

• Nonswaged barrel design allows flush surface contact for welded mounting
• Nonremovable pin provides added security and prevents disassembly
• Cold-rolled steel hinge body and steel pin for consistent material hardness
• Heavy-duty construction rated for demanding surface-mount applications
• Plain steel finish accepts field-applied paint or coating after weld installation
• Compact 2 x 2 inch leaf size fits tight installation spaces

Compatibility

Designed as an OEM-style weld-on replacement hinge for metal fabrication assemblies requiring a nonswaged, fixed-pin surface hinge in a 2 x 2 inch leaf size.

Installation Notes

Installation is performed by welding professionals using MIG, TIG, or stick welding equipment appropriate for the base metal thickness. Clean and deburr the mounting surface before tacking to ensure full weld contact across the hinge leaf. Allow the weld and surrounding metal to cool completely before cycling the hinge under load. Apply primer and finish coat after welding if corrosion protection is required for the operating environment.
