Wichard 65361W Black Watertight U-Bolt 12mm Diameter x 110mm Length Marine Deck Fastener

The Wichard 65361W Black Watertight U-Bolt is a professional-grade marine deck fastening solution engineered for reliability in demanding marine environments. Measuring 12mm (15/32") in diameter and 110mm (4-21/64") in length, this U-bolt is purpose-built for secure attachment of shrouds, lifelines, blocks, and other critical deck hardware.

A key innovation of this design is its watertight black rubber collar (boot), which seals around the deck penetration to eliminate water ingress, noise, leaking, and vibration — with no messy silicone sealers required in most installations.

Key Features:

• Fully drop-forged from high-quality 316L marine-grade stainless steel for maximum corrosion resistance
• Watertight rubber collar creates a positive deck seal — no sealant needed
• Outstanding working and breaking load ratings suited for critical rigging applications
• UV-resistant black rubber boot for long-term outdoor durability
• Metric threads for a precise, secure fit
• Includes backing plate, nuts, and washers — ready to install
• Suitable for shrouds, lifelines, blocks, and various deck fastening applications

The Wichard 65361W delivers an aesthetically clean, watertight deck installation without compromising strength or reliability. Sold individually.
