Stainless Steel AISI 316 Hinge 180x40mm – Heavy-Duty Marine Hinge

This 180 mm stainless steel hinge is engineered for the dependable support of heavy boat hatches, cabin doors, or large lids. Crafted from high-strength AISI 316 steel, the hinge offers outstanding corrosion resistance even with constant exposure to saltwater and outdoor conditions. Its heavy-duty construction and thick 1.75 mm leaves ensure the hinge can handle substantial loads and shocks from waves or vibrations without bending or losing alignment.

The two-leaf design allows the attached hatch or door to swing open to roughly 180°, providing completely unobstructed access – a crucial feature when loading gear or servicing equipment through a large opening. The pre-drilled mounting holes are countersunk so that the screw heads sit flush and don’t protrude. This not only gives a professional, clean look after installation, but also removes any chance of snagging lines or causing injury to crew. The hinge is suitable for both exterior deck installation and use in wet below-deck areas, maintaining its smooth operation and structural integrity even in harsh marine environments.

• Recommended Use: Large deck hatches, engine room or cargo hold covers, as well as entry doors on boats approximately 6–10 meters in length, where reinforced hardware is required.
• Install in Pairs: While a single hinge can support smaller lids, using two or more hinges on bigger hatches and doors is recommended to distribute weight evenly and ensure smooth, safe opening.
• Suitable For: Sailing yachts, motorboats, fishing vessels, and workboats where the reliability of deck hardware is critically important.
• Durability: Even under constant outdoor exposure (sun, rain, saltwater), this hinge retains its performance – ideal for boats that frequently operate in rough conditions or are used commercially.
