Step bolts are literally used as steps on steel communication and electrical transmission towers. These bolts are generally provided with two. One nut is tightened against the thread run out. The unthreaded shank, or step length, typically ranges from 6" to 10".
Step Bolts are similar to Carriage Bolts in that they both have a square shoulder and a larger bearing surface. Step bolts, however have a larger and lower-profile round head creating a smooth surface. The larger head also makes it more difficult to be pulled through soft materials it is usually applied to. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
