Stainless Steel Hinge 42 x 42 x 3.5 mm – Compact AISI 316 Marine Hinge

This compact 42 x 42 mm hinge is an excellent choice for small openings and covers on your boat. Made entirely of marine-grade AISI 316 stainless steel, it offers top-of-the-line protection against rust and corrosion – even under constant exposure to saltwater and humidity, the material retains its strength and appearance. This means the hinge is suitable for use both in the interior of the yacht and for exterior mounting on deck or in the cockpit.

With its 42x42 mm size and 3.5 mm thickness, this hinge is intended for lighter-duty applications – perfect for access hatches to small compartments, console lids, electrical panel covers, cabinet doors in the cabin, or small storage compartment lids. The mirror polish of the stainless steel not only provides an attractive shine but also reflects UV rays, which can reduce heat buildup, and makes the surface easier to clean of salt and grime.

The hinge is designed for hassle-free installation and operation: it has four pre-drilled holes sized for standard stainless steel wood screws or bolts with countersunk heads – this ensures that once mounted, the screw heads sit flush and won’t snag. It’s advisable to use a sealant (e.g., silicone or polyurethane) under the hinge for exterior installations to prevent water ingress through the screw holes. The hinge pin is securely fixed (riveted or welded in place), which prevents any accidental disassembly and provides smooth rotational movement. When properly installed, the hinge exhibits no play, and the motion remains smooth throughout its life with no squeaking – even after years of exposure to marine conditions.

Use Cases and Recommendations:

• Small deck hatches and inspection ports: This hinge is great for little access panels that allow reach into fuel filters, pumps, or storage cubbies. Its compact size makes it unobtrusive yet sufficiently strong for the purpose.
• Cabinetry and furniture in the cabin: Ideal for cabinet doors, small lockers, drawers, or fold-down tables in the yacht’s interior. The gleaming stainless finish complements marine interiors nicely and won’t rust in the damp environment of the cabin or galley.
• Equipment covers and panels: Can be used to attach lids on electrical distribution panels, battery boxes, or onboard toolboxes. Its small footprint means it doesn’t take up unnecessary space or draw attention.
• Boats up to ~5 meters: For smaller boats where hatches and doors are also small and subject to moderate forces, this hinge is perfectly adequate. For larger or heavier hatches, you might consider larger hinges from the same series (e.g., 62x62 mm size).
• Non-marine uses: Thanks to its high corrosion resistance, the hinge can also be utilized beyond the boat – for example, in outdoor furniture, garden boxes, near-pool equipment, etc., where ordinary hinges would rust quickly. Here, the AISI 316 stainless will provide long-lasting performance with no rust.
