Professional Grade Marine Hardware
Engineered for the uncompromising demands of the maritime environment, this Heavy-Duty 316 Stainless Steel Butt Hinge offers unparalleled durability. Unlike standard stamped hinges, our 4.5mm solid cast construction provides superior load-bearing capacity for heavy deck hatches, cabin doors, and storage lockers.
Technical Precision
- Marine-Grade Metallurgy: Forged from high-nickel 316 Stainless Steel for maximum chloride corrosion resistance.
- Mirror-Polish Finish: High-gloss surface reduces salt crystal adhesion and repels grime for easy maintenance.
- Heavy-Duty Casting: A robust 4.5mm thickness ensures zero deformation under stress, outperforming 2mm alternatives.
- Universal Application: Ideal for fiberglass, wood, and aluminum hull configurations.
Precision-engineered at 50mm x 50mm (2" x 2"), this hinge is the definitive choice for yacht restoration and premium vessel construction.
Frequently Asked Questions
- Can this hinge be used for exterior hatches exposed to direct saltwater spray?
- Absolutely. This hinge is manufactured from solid cast 316-grade stainless steel, which contains molybdenum to specifically prevent pitting and crevice corrosion in high-chloride saltwater environments.
- Is this hinge stamped from a sheet or is it a solid cast part?
- This is a 4.5mm solid cast hinge. Unlike thin stamped alternatives that can bend or fail under heavy loads, our cast construction ensures structural integrity for heavy deck cabinets and engine hatches.
- Does the mirror finish require special cleaning to prevent rusting?
- The mirror-polished finish is achieved through a multi-stage buffing process that seals the metal's surface pores. It naturally repels grime and salt, requiring only a simple freshwater rinse to maintain its luster.
