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.

Our relationships with factories all over the United States and abroad based on decades of custom hardware & fastener production history, in combination with the flexibility of blanket purchase arrangements, allows us to fully cater to the customer’s hardware specification and procurement requirements.
