This 80x40 mm stainless steel hinge is made from AISI304 grade steel, making it an excellent choice for applications that require reliability and corrosion resistance at an optimal cost. With a thickness of 2 mm, the hinge provides sturdy support for attached components and remains stable over time without loosening or bending under normal use. Its polished finish adds both to its aesthetics and functionality – the surface is smooth and free of sharp edges, giving your installation a professional look.
The 80x40 mm size is a versatile fit for many onboard tasks: you can use this hinge for under-deck cabinets, small access hatches to storage compartments, electrical panel covers, or interior furniture doors in the cabin. It’s robust enough to securely support medium-sized doors and lids, yet compact enough to fit in limited spaces.
Although AISI304 has slightly lower chloride resistance than marine-grade 316, this hinge performs very well in damp and salty environments, especially when installed in protected areas or rinsed with fresh water as part of routine maintenance. This makes it suitable for interior locations on the boat or above-waterline areas – for example, in the cabin, heads (bathrooms), galley cabinets, as well as for lids of bait or fish boxes that are not constantly submerged in saltwater.
Installation is standard – the hinge comes pre-drilled with countersunk holes (typically 4 corner holes). When replacing an existing 80x40 mm hinge, the hole spacing will likely match, allowing an easy swap. The AISI304 stainless hinge (80x40x2 mm) offers a combination of durability, clean appearance, and affordability, making it a go-to component for the construction or repair of a wide range of boats.
