The Sugatsune 304B-C46/19 is a self-close concealed hinge built from 304 stainless steel, designed for 3/4 inch overlay doors on both face-frame and frameless cabinets where corrosion resistance and long-term durability are priorities.
Most cabinet hinges are plated steel, which holds up well in a dry kitchen or living space. The 304B-C46/19 is built for the environments where plated steel eventually struggles: outdoor kitchens, wet bars, bathroom vanities, marine cabinetry, commercial food-service casework, and any space that sees regular humidity, moisture, or salt air. The 304 stainless body resists corrosion from the material up, not from a surface coating that can wear or chip. The 35mm cup bores into the door in the standard way, and the arm screws to a base plate mounted to the cabinet, ordered separately. Match the plate to your cabinet construction and the 304B series.
Sugatsune is an industrial hardware maker, and the 304B series reflects that lineage: the hinge is machined stainless throughout rather than stamped steel with a finish layer. The self-close mechanism is a spring that pulls the door closed over the last few degrees of travel. It is not a soft-close damper, so the door closes with a firm, positive contact rather than a cushioned settle. That is the correct choice for applications where simplicity and mechanical reliability matter more than a quiet close, such as commercial cabinetry, utility spaces, and outdoor installations where damper mechanisms can degrade. The 43mm boring pattern is specific to this series, so confirm it against your door's existing bore before ordering replacements.
Cabinet shops and contractors specifying for wet or coastal environments will find this hinge does the job other hinges require extra protection for. It suits face-frame and frameless boxes equally, so it works across a full project without switching hinge families. The screw-on mount is deliberate: a mechanical screw connection holds long-term in conditions where a clip-on arm might loosen from thermal cycling or vibration. Homeowners renovating an outdoor kitchen or a boat interior, and designers specifying a bathroom vanity that will see daily water exposure, are all looking at the right hinge. For a dry interior application, the nickel or black nickel versions in this family offer the same self-close geometry at a lower price point.
No. The hinge arm screws to a base plate that mounts to the cabinet, and the plate is sold separately. Use a plate matched to the 304B series and your cabinet construction type.
No. It is a self-close hinge: the spring draws the door shut firmly over the last few degrees. It does not cushion or slow the close the way a soft-close damper does.
This hinge uses a 43mm boring pattern, which differs from the 45mm pattern common on many European hinges. If you are replacing an existing hinge, measure the center-to-center spacing of the screw holes beside the cup before ordering to confirm it matches.
The rated capacity is 11 lb per pair. For heavier doors, add hinges and reference the manufacturer load table to set the correct count for your door size and weight.
Specify this hinge where the environment asks more of the hardware than a standard plated hinge can deliver, and where a firm, mechanical close and a dependable stainless build are what the job requires.
