These are 9 different custom large plain steel u-bolts we supplied our customer in the Kansas City, MO area. Quantities ranged across the nine different sizes but all shared the 3/4-10 diameter and thread pitch, as well as the plain A36 steel material. The largest size pictured with Leonid here measured 42 inches on the inside width and 39-1/16 on the inside length. 8 inches of 3/4-10 thread was incorporated on each side.
