ABSTRACT:
A universal offset pulling head assembly for exerting an axial pulling force on a fastener allows the same pulling head assembly to be utilized for a variety of different fastener sizes and types by exchanging a front plate assembly, where the front plate assembly may comprise variable nose pieces according to the type of fastener to be installed. Because the front plate assembly is subject to the most severe wear, other components of the pulling head assembly may continue to be utilized and the front plate assembly discarded. The disclosed pulling head assembly utilizes a stationary guiding member which prevents damage which might otherwise occur because of severe bending moments.
