These are custom A108 steel u bolts domestically manufactured with rolled thread.  The picture shows the initial sample pieces made in plain ASTM A108 steel material for testing purposes, with the production order consisting of zinc plated version of the same part.  The lead time for these custom round u bolts is slightly longer than usual, at 6-8 weeks from order confirmation.  Material certs and cert. of conformance are available upon request and a rush order option is available if a similar u bolt is ever needed in a hurry.

The inside width is set at 1.01-1.04", taking into account the drawn out material for the rolled thread.  Inside depth is set at 1.84" and approximately .62" of thread is incorporated on each leg.  Large quantities of these custom made A108 steel u bolts would be best supplied on a 12 month blanket purchase order basis.  The Blanket Order concept allows the customer to access the large quantity cost savings without paying upfront for the entire large quantity order. Instead we take on the burden of carrying the bulk inventory and only release the parts as needed, or often on a pre-scheduled basis provided by the customer.
