ABSTRACT:
Thus, the present device provides a nut and bolt assembly having a lower threaded end and opposing upper threaded end. A first flange seats above the lower threaded end and an upper flange seats below the upper threaded end. A weak point having a known torque limit is provided below the upper flange. A nut is mounted on the upper threaded end. When the nut is turned beyond the torque limit of the weak point, it causes the bolt to break at the weak point. The bolt of the present invention is relatively inexpensive to make and use. It is designed preferably to be used in conjunction with a pressing member and a pipe junction holder for holding a pair of joined pipes.
