U-Bolts are available in PLATED (ZINC), GALVANIZED, and STAINLESS STEEL. However, most sizes are not available in all materials. All U-Bolts are priced with and include nuts and lock washers.
We hope this clarifies how u-bolts are measured the two most important measurements are the width and length of leg, MEASURED FROM THE INSIDE OF THE U-BOLT. Most metal on trailers is either 2” or 3” the U-bolts for these is always 1/16” wider between the legs.
