Seachoice U-Bolts

Seachoice U-Bolts: Dependable Marine Fastening Hardware

When it comes to keeping your boat and trailer rigged securely, the quality of your hardware matters as much as any other component on the water. Seachoice has been a trusted name in marine hardware since 1988, and their lineup of U-bolts reflects the same commitment to durability and practicality that has made the brand a go-to choice for boaters across the country.

Built for the Marine Environment

Seachoice U-bolts are constructed from solid galvanized steel, a material choice that speaks directly to the demands of the marine environment. Galvanization creates a zinc-barrier coating that resists rust and corrosion — critical properties for hardware that regularly faces moisture, salt spray, and road grime during trailering. Each U-bolt ships complete with matching nuts and lock washers, so you have everything needed for a secure, rattle-free installation right out of the package.

Seachoice offers both square and round profile U-bolts, covering a wide range of fitment needs. Square U-bolts are particularly well-suited for flat surfaces and bunk boards, while round U-bolts conform neatly to cylindrical elements like pipe rails or roller assemblies. With 14 distinct SKUs spanning multiple dimensions — from compact sizes like 1-5/8" x 3-9/16" to larger spans like 3-1/16" x 3-7/8" and 2-3/8" x 5-3/8" — there's a Seachoice U-bolt sized to handle most common trailer and marine hardware applications.

A Brand Built on Marine Hardware Expertise

Seachoice launched in 1988 supplying foundational marine hardware — cleats, hinges, and hasps — and has since grown to offer more than 6,000 parts across 17 product categories. That deep catalog means their U-bolt line doesn't exist in isolation; it's part of a cohesive ecosystem of marine hardware designed and tested to work together. Backed by a no-hassle warranty and distributed from 18 global warehouse locations, Seachoice products are built for boaters who value reliability without compromise.

Where Seachoice U-Bolts Fit In

U-bolts are workhorses of boat trailer hardware. They're commonly used to secure bunk boards, attach guide posts, mount keel rollers, and anchor tie-down straps. Because they're subjected to repeated stress during loading, transport, and launching, choosing a fastener made from quality galvanized steel — rather than bare or plated steel — can dramatically extend the service life of your trailer rigging. Seachoice's decision to include lock washers in every pack reflects an understanding of the vibration loads trailers experience on the road.
