Abstract
A step bolt connector and bolt assembly creates steps on a structure for accommodating a worker's boot. A first threaded bore is formed in a cylindrical end of a step bolt connector and this first threaded bore is threaded onto an exposed bolt on a structure. A sight hole extends from the exterior of the connector to the inward end of the first threaded bore for visually checking to see if the bolt is adequately attached in the first bore. A recess is formed in the cylindrical end and the recess is dimensioned to fit over fastening nut on the exposed bolt on the structure. When the first threaded bore is screwed onto the exposed bolts on the structure, the recess at least partially surrounds shields and protects the fastening nut on the exposed end of the bolt. A second threaded bore is formed in a second end (a truncated conical end) of the connector, and a step bolt is secured in the second threaded bore. The step bolt is dimensioned so that the step bolt when fastened to the connector forms a step on the structure having a length greater than the width of the workers boot. In this manner, a convenient step is formed on the structure for use in climbing the structure to perform r…
