Tie Down 86223 Galvanized Square U-Bolt, 1/2 in.-13 Thread, Fits 2 in. Square Trailer Frame

The Tie Down 86223 is a galvanized square U-bolt sized to fit 2 in. Square trailer frame tubing, sold individually (each). It is built with a 1/2 in.-13 thread and measures 2-1/8 in. Wide by 4 in. Long, making it a direct fit for axle, leaf spring, and frame mounting applications that call for this thread pitch and square bend profile. The galvanized finish provides corrosion resistance for trailers used in wet, road-salt, or marine-adjacent environments where rust is a constant concern.

Square U-bolts like the 86223 are commonly used to clamp leaf springs to trailer axles, secure roller brackets and bunk brackets to a square trailer frame, or mount other hardware where a square-bend U-bolt is required rather than a round one. Because it is sold as a single unit, buyers needing a matched pair for a bracket or spring installation should order two, or select Tie Down's pre-packaged pair option for the same dimensions.
