When reliability and corrosion resistance are non-negotiable, the Dunn & Watson 316 Stainless Steel Casted Boat Butt Hinge delivers unmatched performance in both marine and 4WD environments. Designed with longevity and strength in mind, this hinge is made from premium 316 stainless steel, offering excellent resistance to salt spray, moisture, and chemical exposure.
Unlike stamped or welded alternatives, this hinge is investment casted for superior structural integrity and a clean, uniform finish. That means no weak points, more precise movement, and a hinge that’s ready to endure years of use on boat hatches, toolboxes, canopy doors, or camper trailer compartments.
The fixed pin design ensures consistent hinge action over time, even under heavy loads or in extreme outdoor conditions. Its sleek polished finish adds to its professional appearance, making it equally suitable for visible exterior applications as it is for functional, hard-working areas.
Whether you’re building out a 4×4 canopy, upgrading a marine hatch, or outfitting a caravan toolbox, this casted butt hinge brings strength, style, and serious weather resistance to your setup.
