Stainless Steel Hinge 83 x 30 mm – Narrow Elongated AISI 316, Heavy-Duty

This 83 x 30 mm stainless steel hinge stands out with its narrow, elongated shape, making it ideal for applications where width is limited but a longer hinge is needed to distribute forces. For example, if you have a tall, slim locker or door, this hinge will provide support along its entire length. It’s also suitable for rectangular deck hatches, where a longer hinge can better handle the stress of opening/closing than two small hinges would.

Manufactured from high-quality AISI 316 stainless steel, this hinge will not rust or degrade even if permanently exposed to saltwater, rain, and UV rays. The thickness is around 3 mm (possibly ~3.5 mm at its thickest), giving it a solid profile resistant to twisting and bending. This hinge can support the weight of heavier lids or doors – for instance, a door to a fish hold or a bilge access hatch – without bending or sagging.

The mounting holes are four in number, distributed along the length, which ensures a stable attachment to the substrate – the length allows screws to anchor at multiple points, reducing stress around each hole. The holes are countersunk so that screw heads sit flush with the hinge surface, providing a clean look and preventing snags. It’s recommended to use stainless steel fasteners (screws or bolts) with this hinge to maintain the full corrosion resistance of the assembly.

The pivot mechanism itself is built with a strong central pin, which guarantees steady movement without play. Despite the hinge’s extended length, the motion is smooth across the entire span and there’s no “twist” when opening – both leaves of the hinge remain aligned and move in unison. This is important for long hinges, as any twisting could cause binding or squeaking.

Use Cases and Recommendations:

• Narrow, tall cabinets or panels: If you have a rod locker, equipment cabinet, or electronics panel that is narrow in width but tall, one elongated 83x30 mm hinge mounted vertically will provide stable support along the full height of the door, rather than using multiple small hinges.
• Rectangular deck hatches: For certain deck openings (e.g., a rectangular hatch to a storage area or tank), one or two of these hinges along the longer side can be used instead of multiple smaller ones – this simplifies the design and distributes the load evenly.
• Folding tables and seats: Yachts often have flip-up tables or seats (in the cockpit or salon). This narrow hinge can be ideal for such uses where the mounting base is slim. It gives the needed length for strength without protruding beyond the edge of the tabletop or seat.
• Medium-sized boats (~5–8 m): On medium-sized powerboats and yachts, there are typically medium-sized hatches and panels. This hinge is a good fit for fish hold lids, fuel filling compartment doors, or engine well covers on boats in this range, where forces aren’t extreme but require something sturdier than the smallest hinges.
• Other outdoor structures: Due to its resilience, the hinge can be used on land as well – for example, in aluminum/stainless equipment boxes, narrow pump house doors, or other technical outdoor installations. Its elongated profile will offer reliability where space for width is limited.
