Tower Bolt
These Tower bolt are commonly used as steps on steel communication and electrical transmission towers. Typically, these bolts are supplied with two 4.6 Grade, 5.8 or 8.8 Grade with normal hexagon nut. One nut is secured against the thread run-out. The unthreaded shank, or step length, generally ranges from 6″ to 10″. These bolts are versatile and employed in various applications, including steel communication and electrical transmission towers, tower reinforcement, and other fastening tasks. High-quality made from low carbon steel and are designed for high strength, making them ideal for use with heavy hex nuts.
Tower bolt are named for their use as climbing on communication and utility poles and towers. They also serve to fasten wood to wood and wood to metal. As part of the round head bolt family, feature a large circular head with a low rounded top surface and flat bearing surface, along with an integrally formed square neck under the head. Similar to carriage bolts and often preferred for decking and softwood applications due to their lower profile head, which is less obtrusive, and their larger head diameter, which reduces the risk of pull-through. Since the head is designed not to turn, step bolts are typically tightened by torquing the nut. When the head is exposed, they can be used with an internally threaded (tapped) hole and tightened by turning the square neck of the step bolt.
