1. A method of connecting a mandrel of a hydraulic fracturing plug to another mandrel, comprising:
providing the mandrel of the hydraulic fracturing plug with a set of shear pins;
inserting a mating collar of the other mandrel over the shear pins of the hydraulic fracturing plug;
rotating one or more of the mating collar of the other mandrel and the mandrel of the hydraulic fracturing plug such that the shear pins rotate toward an end position of a pin track of the other mandrel; and
inserting a master pin through at least a portion of the mating collar of the other mandrel and the mandrel of the hydraulic fracturing plug such that the master pin precludes rotation between the mating collar of the other mandrel and the mandrel of the hydraulic fracturing plug.
