Cabinet Door Hinges

On board, saltwater and constant humidity put every moving element to the test. A hinge made from a less resistant alloy oxidizes quickly, seizing the door or staining the gelcoat with unsightly rust streaks. The choice of material is the first step: AISI 316 remains the benchmark for corrosion resistance, thanks to its molybdenum content that protects the alloy from chloride attack.

When selecting a hinge, always look at the mounting type: flush, overlap, or folded. An incorrect hinge can prevent the airtight closure of a locker or put excessive stress on the fastening screws. Always verify the load rating of the backing: heavy doors in teak or marine-grade plywood require pins with larger diameters and metal thicknesses that do not flex under load.

At Nautiba, we verify that the technical details match your actual needs. If you have questions about compatibility or load capacity, we help you compare the technical data before confirming your order. Our working approach is based on transparency: if a component is not suited to your specific application, we will tell you right away, avoiding wasted time and unnecessary return costs.

How to Choose the Right Hinge

• Prefer AISI 316 for every exterior installation subject to direct spray.
• Verify that the pin diameter is proportional to the weight and frequency of use of the door.
• Consider the clearance when the door is at maximum opening.
• Always check the number of holes and the screw diameter to ensure a stable mechanical fastening.

Why prefer AISI 316 stainless steel over AISI 304?

AISI 316 stainless steel contains a percentage of molybdenum that increases corrosion resistance in chloride-rich environments typical of marine water, making it clearly superior to AISI 304 for on-board longevity.

What should I do if the hinge has excessive play?

If the pin shows play, the hinge is worn and must be replaced. Attempting to restore it with lubricants does not resolve the mechanical problem and risks seizing the door in critical conditions.

Are gaskets necessary under the hinge?

Using a rubber or plastic gasket between the hinge and the backing helps isolate the metals and prevent water infiltration inside the locker, protecting the structure.

How do I prevent rust on the fastening holes?

Make sure to use only stainless steel fasteners of the same grade as the hinge and, when possible, apply a polyurethane marine sealant in the holes before screwing to fully isolate the backing.

What information is needed for a technical check?

To confirm compatibility, always provide the fastening hole dimensions, the thickness of the material you will mount the hinge on, and the approximate weight of the door to be moved.
