Deck Hardware • Top Pick
Check PriceNothing disrupts the serene aesthetic of a well-appointed deck quite like the unsightly orange bleed of a failing hinge. You’ve spent hours curated the perfect atmosphere on your boat, only to have the visual harmony shattered by hardware that can’t withstand the elements. It’s more than just a blemish; it’s a sign that the structural integrity of your hatches and doors is being compromised by the very environment they were meant to enjoy.
Choosing generic hardware is a common pitfall in restoration projects. These inferior alternatives, often made from low-grade alloys, quickly succumb to the relentless assault of salt air. Within a single season, you’ll notice pitting, a loss of luster, and eventually, the terrifying creak of a hinge seized by oxidation. These cheap components don't just look tired; they fail when you need them most, leading to leaks that damage your interior woodwork and costly repairs that could have been avoided with a more discerning eye for quality.
True luxury lies in the details that perform as beautifully as they look. The Marine Grade 316 Stainless Steel Boat Butt Hinge - Mirror Polished (100mm) is the definitive answer for the sophisticated mariner. Forged with precision, this hinge offers a sculptural quality that elevates any hatch or door into a statement of intentional design. Its mirror-polished finish isn't just for reflection; it provides a protective barrier that maintains its brilliance against the harshest maritime conditions, ensuring your vessel remains a sanctuary of comfort and style.

Technical Glossary
- Grade 316 Stainless Steel
- A premium austenitic chromium-nickel stainless steel that contains molybdenum, providing superior resistance to marine corrosion and pitting.
- Electro-Polishing
- An electrochemical process that removes surface material from the metal, creating a microscopic smoothness that enhances the mirror-like shine and prevents salt crystals from adhering.
FAQ
- Will this hinge develop rust or pitting in saltwater environments?
- No, this hinge is forged from authentic Grade 316 stainless steel, which contains molybdenum specifically for resistance against chloride-induced pitting. The electro-polished mirror finish further seals the surface to prevent salt accumulation.
- Is this hinge strong enough for heavy anchor locker or deck hatches?
- Yes, unlike thin-stamped hinges, this unit uses precision drop-forged heavy-duty casting. It is engineered to maintain structural integrity and zero deformation even under the weight of heavy fiberglass hatches or high-traffic doors.
- What are the exact dimensions for mounting hole alignment?
- The hinge features four 5.5mm countersunk holes. The vertical distance between holes on each leaf (D) is 27.0mm, and the total length (A) is 101.5mm. This standard sizing allows for universal replacement of most OEM boat hinges.
