AAA Stainless Steel Hinge – 304 is a compact, elongated hardware hinge designed for mounting doors, lids, access panels, lockers, cabinets, and similar hinged components. Manufactured from stainless steel 304, it offers practical corrosion resistance and a clean metallic appearance for marine, boating, and general hardware installations. Its narrow 37.5mm profile is particularly useful where the available mounting surface is limited, but a longer hinge footprint is preferred.

The hinge measures 104.8mm x 37.5mm x 2mm and has a flat, surface-mounting configuration. Its two unequal leaves create a short-side strap-hinge design, allowing the longer leaf to distribute the mounting points across a larger section of the attached panel. The rounded ends produce a neat installed appearance and help the hinge fit smoothly onto boat cabinetry, storage compartments, inspection covers and other equipment. When installed correctly, the central hinge joint enables the connected door, lid or panel to open and close around a fixed pivot point.

Five 5.3mm countersunk mounting holes are positioned across the hinge leaves. Three holes are located on the longer leaf, while two are positioned on the shorter leaf. The countersunk-hole design is intended for compatible countersunk fasteners, allowing the screw heads to sit more evenly with the hinge surface. Fasteners are not specified, so the installer should select screws or bolts that match the hole size, mounting material, panel thickness, and intended application. Correct alignment of both leaves is important for smooth movement and an even finished installation.

This stainless steel boat hinge can be used as a surface hinge or fitted in a flush arrangement when the installation structure permits. Its slim format makes it suitable for boat doors, marine lockers, storage lids, cabinet doors and access panels. It may also be considered for yacht interiors, boat cabins, utility compartments, equipment enclosures and selected exterior hardware installations. The actual mounting position should always be evaluated according to the panel dimensions, operating movement, load, and exposure conditions.

Stainless steel 304 is commonly selected for hardware because it combines corrosion resistance, strength and an easy-to-maintain surface. Regular cleaning remains important, particularly when the hinge is exposed to salt deposits, moisture, cleaning chemicals, or outdoor contamination. Rinsing with fresh water and wiping the hinge dry can help maintain its appearance. For continuously wet, submerged or highly aggressive saltwater locations, the installer should confirm whether grade 304 is appropriate for the specific environment before installation.

With its recognisable five-hole layout, rounded profile and practical dimensions, this hinge provides a straightforward hardware solution for new installations, replacements and refurbishment projects. Buyers replacing an existing hinge should compare the complete dimensions, hole diameter, hole arrangement and available mounting area rather than relying only on the overall length. The product is identified as AAA part number 52573, helping purchasers distinguish it from other AAA stainless steel hinges with different measurements.
