Tie Down Engineering 86208 Square U-Bolt, 3/8 in.-16 x 4 in., 1-3/4 in. Width, Pair

The Tie Down Engineering 86208 is a square U-bolt sold as a pair, built for trailer roller bracket and axle mounting applications. Each U-bolt measures 4 inches in length with a 1-3/4 inch width across the square bend, and is threaded 3/8 in.-16 on both ends to accept standard hex nuts. Constructed from alloy steel rated to Grade 8.8 hardness, the 86208 is engineered to handle the repeated load and vibration stress common on boat trailers, utility trailers, and roller bracket assemblies. The threads are cut Unified National Coarse (UNC), right-hand, full thread, class 3A, so they mate cleanly with standard 3/8 in. Hardware. A matte or brushed finish resists surface wear during installation and field use. Because this is a square-bend U-bolt rather than a round-bend, it is intended for square tube or square bracket stock rather than round pipe or round axle housings. The pair is sold together so both mounting points on a bracket or roller assembly can be replaced or upgraded at the same time with matching hardware. This part carries a full manufacturer's warranty.
