Cast Stainless Steel Hinge 102x25 mm (AISI 316) – Heavy-Duty Marine Hinge

This cast stainless steel hinge measuring 102x25.4 mm combines an elongated form with exceptional strength. Precision-cast from AISI 316 alloy, the hinge has a one-piece structure with no welds, eliminating weak points and allowing it to handle heavy loads. The narrow width (25 mm) makes it suitable for situations where installation space is tight or a sleek, unobtrusive profile is desired – for example, on cabinet doors, folding tables, or transom gates.

At 5 mm thick, this hinge is significantly more robust than standard sheet-metal hinges. It withstands strong impacts and stresses, including the weight of heavy lids or frequent opening and closing. Corrosion resistance is outstanding – even with constant exposure to seawater and sun, the material maintains its integrity. This hinge is often chosen for professional and commercial applications (such as rescue equipment lockers, ship hatches, industrial yachts) where safety and longevity are paramount.

• Applications: Ideal for heavy doors and lids – e.g., cabin entry doors, transom gates, large locker or chest lids that must bear significant weight
• Suitable for folding structures (tables, platforms) on yachts, where a strong hinge prevents sagging or breakage after repeated use
• Commonly used in high-demand marine settings – fishing vessels, commercial craft – where hardware must endure years of service without failure
• Installation requires appropriately strong fasteners (stainless bolts); it’s recommended to periodically lubricate the hinge pin under heavy use to ensure smooth operation
