Boat Trailer U-Bolts & Mounting Hardware
Boat trailer U-bolts are used to secure critical components like axles, leaf springs, bunk brackets, roller assemblies, and frame hardware. This collection includes EZ Loader U-bolts and mounting hardware designed for proper fit and long-term durability.
These are load-bearing fasteners. Using the correct size and type is critical for keeping your trailer aligned and secure on the road.
Where U-Bolts Are Used
U-bolts are commonly used to mount:
• trailer axles to leaf springs
• bunk brackets to cross members
• roller assemblies and rocker arms
• guide poles and frame components
Many EZ Loader trailers use different U-bolt sizes depending on the frame and axle configuration.
Choosing the Right U-Bolt
When selecting a U-bolt, match:
• inside width (frame or axle size)
• leg length
• thread size (commonly 1/2"-13 or 3/8")
• material (zinc plated, galvanized, or stainless steel)
Getting the wrong size can lead to loose components or improper mounting.
Common Sizes and Applications
Examples include:
• 1/2" U-bolts for axles and heavy mounting points
• 3/8" U-bolts for roller arms and lighter hardware
• square U-bolts for trailer frames
• round U-bolts for axle mounting
When to Replace U-Bolts
Replace U-bolts if you see:
• rust or corrosion
• stretched threads
• damaged or bent hardware
• loose or shifting components
U-bolts are inexpensive, but critical to trailer safety.
