Professional Grade Marine Rigging Hardware
Engineered for extreme durability, this Long D Shackle is forged from premium 316 Marine-Grade Stainless Steel. Featuring a precision-threaded captive screw pin, it provides superior resistance to saltwater corrosion and high-load stress. The elongated D-shape geometry is optimized for specialized rigging, towing, and architectural applications where standard shackles lack the necessary reach.
- High-Tensile Strength: Load rated from 100kg to 1200kg based on size.
- Mirror Polish Finish: Electropolished surface ensures maximum corrosion resistance and aesthetic appeal.
- Versatile Sizing: Available in M5, M6, M8, M10, and M12 to suit diverse marine and industrial needs.
Frequently Asked Questions
- Will this shackle rust in saltwater environments over time?
- No. Visual forensics of the mirror polish finish and the 316-grade material specification indicate a high chromium and molybdenum content, which provides a passive oxide layer specifically resistant to chloride-induced pitting and crevice corrosion common in ocean environments.
- Is the screw pin secure enough for high-vibration engine-adjacent areas?
- Yes. The precision-threaded captive pin mechanism is engineered with tight tolerances to ensure a vibration-resistant lock. For critical high-vibration applications, the eye of the pin allows for safety wiring to prevent accidental unscrewing.
- Can this be used for overhead lifting in industrial settings?
- The M5-M12 range is load-rated from 100kg to 1200kg as per the specification chart. For industrial lifting, ensure the Working Load Limit (WLL) of the chosen size matches your rigging requirements, as the forged 316 steel provides high tensile strength but must be used within its rated capacity.

Our Roots
Hong Kong Based, 8 Years of Expertise
The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.
Supply Chain
Invested Factories in Mainland China
To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
