Professional Marine-Grade Towing Hardware
Secure your vessel with our 316 Stainless Steel Bow and Stern Eye U-Bolts. Specifically engineered for the rigorous demands of marine environments, these U-bolts are constructed from passivated marine-grade stainless steel to provide maximum corrosion resistance against harsh saltwater. The mirror-polished finish not only enhances aesthetics but adds an extra layer of protection against pitting and staining.
Technical Engineering & Durability
- Structural Integrity: Designed for transom mounting, providing the high-tensile strength required for ski tows and heavy load distribution.
- Vibration-Proof Security: Each kit includes heavy-duty stainless steel washers and nylon-insert hex lock nuts to ensure the hardware remains tight under engine vibration and wave impact.
- Passivated Finish: Advanced chemical passivation treatment removes surface contaminants, maximizing the longevity of the alloy's protective oxide layer.
Whether you are replacing an OEM part or upgrading your towing capabilities, this universal fit hardware provides the safety and reliability needed for high-performance boating.
Frequently Asked Questions
- Will these U-bolts rust when exposed to constant saltwater?
- No. These are forged from 316 marine-grade stainless steel and undergo a chemical passivation process that removes surface iron and contaminants, creating an ultra-durable oxide layer that prevents rust and pitting in saltwater environments.
- Are these strong enough to be used as a primary ski tow point?
- Yes. The rugged construction and thick backing plates are specifically engineered for transom mounting to handle the structural stress of ski tows and heavy towing loads without pulling through the hull.
- Do I need to buy separate locking washers to prevent loosening?
- No. The kit includes specialized nylon-insert hex lock nuts which are specifically designed to resist loosening caused by boat engine vibrations and hull movement in rough water.

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.
