C.E. Smith Zinc U-Bolt 7/16"-14 X 3-1/8" X 4" w/Washers & Nuts - Square

The C.E. Smith Zinc U-Bolt 7/16"-14 X 3-1/8" X 4" w/Washers & Nuts is a heavy-duty fastening component designed for trailer frames, vehicle suspension systems, and custom automotive applications where secure clamping is essential. This square u-bolt configuration provides the rigid holding power needed to mount frame components, secure cross-members, and stabilize brackets under dynamic loads and vibration.

Whether you're building a custom suspension setup, reinforcing a frame repair, or installing aftermarket components, this zinc-plated fastener delivers reliable performance in both highway and off-road conditions. Built to C.E. Smith's exacting standards, this u-bolt features a 7/16"-14 thread specification with precision-formed square geometry that ensures consistent load distribution across mounting surfaces. The zinc plating provides corrosion resistance in moisture-prone environments, making it ideal for coastal, salt-road, and wet-climate applications.

The 3-1/8" inside width and 4" center-to-center leg spacing accommodate standard frame and beam geometries, while the included washers and nuts eliminate trips to the hardware store and ensure matched material compatibility across your assembly. This u-bolt works across trailer suspensions, frame repairs, custom automotive builds, and industrial equipment mounting where repeatable, centered clamping is non-negotiable. Mechanics and fabricators rely on the square u-bolt profile for its strength and reliability.
