ABSTRACT:
The power wrench of this invention which can powerfully hold, twist or turn a bolt, nut or screwhead is characterized in that the torquing end of the wrench has ratchet means at both surfaces thereof. Due to the above construction the fastening and loosening of bolt means can be readily conducted with a minimum effort of replacement of the parts thereof. Furthermore, since the power wrench is provided with a right-angular arrangement, optimal wrenching is effected.
