Abstract
A split nut and assembly steps for fitting the nut around an exposed portion of anchor bolt having no convenient access for conventional nuts to engage. The split nut includes first and second nut halves, and each nut half has an interior surface having a threaded half cylinder that, when aligned with the other threaded half cylinder and joined along joining surfaces, forms a threaded opening. The two half nuts may be connected by connectors that are inserted into penetrations that extend through at least a portion of both half nuts. At least one end of the penetration extends from the joining surface through the exterior surface of the half nut so that the connector may be inserted into the penetration. The exterior surface of both half nuts also include flat that, when the half nuts are joined, are dimensioned to form opposed parallel drive surfaces configured to be engaged by a wrench for screwing the split nut onto the bolt.
