Whitecap Butt Hinge - 316 Stainless Steel - 1-1/2" x 1-1/2"

The Whitecap Butt Hinge in 316 stainless steel is a marine-grade hardware component designed for applications requiring superior corrosion resistance in harsh saltwater and coastal environments. This 1-1/2" × 1-1/2" butt hinge delivers the durability demanded by offshore vessels, coastal structures, and equipment exposed to continuous salt spray and moisture—conditions where standard steel hinges fail rapidly.

Constructed from 316 stainless steel, this hinge offers enhanced resistance to pitting and crevice corrosion compared to 304-grade alternatives, making it the preferred choice for subsurface or submerged fastening scenarios. The compact 1-1/2" square dimension accommodates standard mounting footprints on panels, doors, and access hatches. Four #10 fasteners (included specification) provide secure anchoring to substrate materials. The butt hinge design allows 180-degree rotation, enabling full swing operation for maintenance access and equipment service on marine vessels, dockside installations, and industrial waterfront equipment.

This hinge is specified by marine engineers, boat builders, and offshore operators who require hardware certified to withstand extended exposure to saltwater spray, high humidity, and thermal cycling. Whitecap marine hardware is purpose-built for applications where corrosion failure is not an option—commercial fishing vessels, military watercraft, coastal defense structures, and desalination plants. Weighing just 0.1 lbs, the hinge adds minimal weight while meeting ASTM B117 salt spray standards expected in maritime hardware specification.
