Marine Stainless Steel Butt Hinge – AISI 316 is a compact marine hardware fitting designed to provide a neat and reliable pivot point for small doors, lids, access panels, cabinets, lockers, and similar hinged components. Manufactured from AISI 316 stainless steel, this marine butt hinge is suitable for installations exposed to moisture, salt spray, humidity, and changing weather conditions. Its corrosion-resistant material makes it a practical choice for boats, yachts, marine interiors, deck compartments, and other environments where ordinary metal hinges may deteriorate more quickly.

The hinge measures 38mm x 38mm (1-1/2″ x 1-1/2″), providing a compact footprint for limited installation spaces. Its traditional butt-hinge configuration consists of two rectangular leaves connected by a central hinge pin, allowing the attached panel or door to open and close through a smooth pivoting action. Four countersunk mounting holes—two on each leaf—allow compatible flat-head fasteners to sit neatly within the hinge surface. This helps create a clean installation and reduces protruding screw heads that could interfere with the movement or appearance of the fitted component. Mounting screws should be selected separately according to the surface material and installation requirements.

AISI 316 stainless steel contains molybdenum, which improves resistance to pitting and crevice corrosion in chloride-containing conditions when compared with commonly used stainless steel grades that do not contain molybdenum. This characteristic makes 316 stainless steel hinges especially relevant for marine hardware applications. However, as with all stainless steel boat fittings, regular cleaning with fresh water and removal of accumulated salt or dirt can help preserve the surface condition. Appropriate installation practices, compatible fasteners, and periodic inspection are also important, particularly in exposed locations.

This marine butt hinge combines a compact size, polished appearance, and marine-suitable construction for functional installations where space and corrosion resistance are important. It can be used as a small boat hinge for cabinet doors, storage compartments, inspection panels, and light access covers, subject to the size, weight, alignment, and required opening movement of the component. Before installation, buyers should confirm that the 38mm x 38mm dimensions, hole positions, and hinge configuration match the intended surface. This model should not be selected only by comparing it with larger heavy duty hinges, as the required hinge size and quantity depend on the actual door or panel.

Key Features:

• Marine Stainless Steel Butt Hinge – AISI 316 provides a compact hinging solution for doors, lids, panels, lockers, and cabinets used on boats and in other moisture-exposed installations.
• Constructed from AISI 316 stainless steel for improved resistance to corrosion in humid, saline, and chloride-containing environments.
• Measures 38mm x 38mm (1-1/2″ x 1-1/2″), making it suitable for small fittings and areas with limited mounting space.
• The traditional butt-hinge design uses two equal leaves joined through a central knuckle and pin to provide a straightforward pivoting movement.
• Includes four countersunk mounting holes, with two holes positioned on each hinge leaf for balanced fastening.
• Countersunk openings are designed to accommodate suitable flat-head fasteners for a neat, low-profile finish.
• Polished stainless steel surface offers a clean appearance that coordinates well with other stainless steel marine hardware.
• Compact rectangular profile makes the hinge easy to position on flat mounting surfaces where the leaves can be correctly aligned.
• Suitable for use as a boat hinge in new installations, marine maintenance projects, hardware replacements, and refurbishment work.
• Can be paired with compatible stainless steel fasteners selected according to the mounting surface and installation conditions.
• Simple hinge construction makes routine visual inspection and cleaning convenient during regular boat maintenance.
• A practical choice for buyers searching for stainless steel butt hinges, a compact marine hinge, or small 316 stainless steel hinges.

Applications / Suitable For:

• Marine Stainless Steel Butt Hinge – AISI 316 is suitable for small boat doors, yacht cabinets, marine lockers, storage compartments, and access panels where its dimensions match the installation.
• Boat interior cabinets and cupboard doors that require compact, corrosion-resistant marine hardware.
• Storage lids, inspection covers, and service-access panels installed in suitable marine interior or sheltered exterior locations.
• Marine furniture, console compartments, equipment enclosures, and utility boxes with compatible flat mounting surfaces.
• Replacement of an existing 38mm x 38mm butt hinge when the overall dimensions, hole spacing, leaf arrangement, and movement are confirmed.
• Boat-building, yacht-refit, repair, and general marine maintenance projects requiring AISI 316 stainless steel hardware.
• Coastal, outdoor, and moisture-prone installations where improved resistance to corrosion is preferred.
• Small hinged components that do not require a concealed hinge, offset hinge, removable-pin hinge, or a different specialist configuration.

FAQs:

Q: What is the size of the Marine Stainless Steel Butt Hinge – AISI 316?
A: The hinge measures 38mm x 38mm, equivalent to 1-1/2″ x 1-1/2″.

Q: Is this marine butt hinge suitable for boats?
A: Yes. Its AISI 316 stainless steel construction makes it suitable for compatible boat, yacht, cabinet, locker, and access-panel installations exposed to marine conditions.

Q: Does the hinge have countersunk mounting holes?
A: Yes. It has four countersunk holes—two on each leaf—designed for compatible flat-head mounting fasteners.

Q: Can this hinge be used for every marine door or hatch?
A: Not necessarily. Suitability depends on the door or panel size, weight, mounting surface, hole positions, required movement, and number of hinges used.
