Frequently Asked Questions
- 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.
