These custom small diameter u-bolts are the more unusual u bolts we have supplied over the years - the one and only time we had to get fully threaded u-bolts manufactured. Typically only a partial length of each leg is threaded, whether cut threads or rolled, but in this case our customer specifically requested a fully threaded version. 2,000 pieces were run through a domestic production process with a lead time of 5-6 weeks. 4-40 thread was incorporated with the inside width at .57 inches and inside length at .75 inches.
