Attwood Marine Bow Eye U-Bolt, Stainless Steel, Plated Nuts and Washers

Overview

This Attwood Marine stainless steel bow eye is a twin-shank U-bolt style fitting for securing a boat at the bow, with plated nuts and washers included for installation. The range covers two common hardware sizes: a 3/8"-16 x 2-7/16" configuration with a 5/16" eye diameter, and a larger 1/2"-13 x 3-1/4" configuration with a 7/16" eye diameter.

The twin-shank layout helps reduce twisting once the bow eye is mounted through the hull or transom structure. It is suited for replacement work on small boats, tenders, runabouts, fishing boats, and trailers where the existing bow eye dimensions and backing arrangement match the selected size.

Key features

• Stainless steel bow eye for exposed boat hardware locations where moisture and spray are part of normal use.
• Twin-shank U-bolt form helps resist rotation when the fitting is loaded from a bow line, winch strap, or transom-mounted tow point.
• Available in two thread sizes and shank lengths to match different hull and mounting thickness requirements.
• Plated nuts and washers are included, so the main fastening hardware needed for installation is supplied with the bow eye.
• Can be used as a transom-mounted ski tow when installed in a suitable structure and within the rated capacity of the selected size.
• Not intended for lifting the boat.

Variants

This product is offered in two configurations for different mounting and load requirements.

The variants differ by eye diameter, thread size, and shank length. Both are stainless steel twin-shank bow eyes supplied with plated nuts and washers.

• 3396-3: Dimension A 5/16"-Dia.; Dimension B 3/8"-16 x 2-7/16". This smaller configuration is a practical match for lighter-duty replacement installations where the existing hole pattern and backing area suit the shorter 3/8"-16 threaded shanks.
• 3392-3: Dimension A 7/16"-Dia.; Dimension B 1/2"-13 x 3-1/4". This larger configuration suits installations that call for a larger eye diameter and longer 1/2"-13 threaded shanks through the mounting surface.

Installation and fit

Before replacing an existing bow eye, compare the thread size, shank length, eye diameter, hole spacing, and backing area on the boat. A bow eye should mount through solid structure with proper washers or backing support on the inside, especially where it will see winch strap loads at the ramp or steady tension from dock lines.

For transom use as a tow point, the surrounding structure and backing must be suitable for the load. The fitting itself should not be used for lifting the boat, and it should be inspected regularly for movement, bent hardware, cracked gelcoat, or corrosion around the mounting holes.

Use on board

This bow eye is a good fit for boat owners replacing worn or undersized bow hardware, restoring a small craft, or matching an existing Attwood-style U-bolt installation. It also works for builders and service yards that need a straightforward stainless steel bow eye with supplied nuts and washers rather than a decorative-only fitting.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
