Professional Marine-Grade Tensioning Hardware
Engineered for extreme environments, the AirowMarine 316 Stainless Steel Eye & Hook Turnbuckle provides uncompromising strength and corrosion resistance. Unlike standard cast hardware, our turnbuckles are precision drop-forged, resulting in superior tensile strength and a high-density molecular structure that prevents brittle failure under high loads.
- AISI 316 Marine Grade: Maximum protection against salt spray and atmospheric corrosion, outperforming 304 stainless in coastal applications.
- High-Polish Mirror Finish: Electropolished surface reduces friction and prevents micro-pitting, ensuring long-lasting durability.
- Smooth Operation: Precision-machined M4 to M20 threads allow for effortless adjustment and exact control over cable tension.
- Versatile Application: Ideal for architectural wire rope railings, marine rigging, yacht hardware, and outdoor shade sail installations.
Each unit features a closed-body design for a streamlined aesthetic and improved safety, eliminating snagging points on ropes or lines.
Frequently Asked Questions
- Is this turnbuckle safe for salt-water marine rigging?
- Yes. Our turnbuckles are manufactured from AISI 316 stainless steel, which contains molybdenum. This specific alloy is designed to resist pitting and crevice corrosion caused by chloride (saltwater) environments, unlike standard 304 steel which will rust in coastal settings.
- Why is 'forged' construction better than 'cast' for my railing?
- Precision forging aligns the internal grain structure of the metal, providing significantly higher tensile strength and resistance to fatigue compared to brittle casting. This ensures the hardware can maintain constant tension on your wire rope railing without stretching or snapping.
- What is the maximum load capacity for the M8 size?
- According to our precision load testing, the M8 turnbuckle has a Working Load Limit (WLL) of 200kg. For heavy-duty industrial or architectural projects requiring higher tension, we recommend stepping up to M12 or M16 sizes which support up to 500kg and 800kg respectively.

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.
Reliability
Strict QC & Global Logistics
As a provider of marine accessories, our business is intimately connected to the water. We believe that protecting the ocean is not just a slogan; it must be reflected in every detail of our business. Currently, AirowMarine is continuously optimizing our packaging solutions: we maximize the reduction of single-use plastics in our packaging and shipping processes, using recyclable paper-based cushioning materials whenever possible. Our products are built to power your voyage, while our packaging is designed to protect the purity of the blue sea.
Our Mission
Protecting the Blue, Plastic-Free
We are aware that there is always room for improvement, but we have never stopped in our pursuit of excellence and environmental responsibility. AirowMarine is committed to providing you with durable, reliable, and eco-conscious marine accessories.
