  • Patent number: 4947712
    Abstract: A wrench-type socket for removing bolts and the like whose head has become damaged or otherwise worn, thus prohibiting its removal by the use of a conventional socket. The present socket has an internal central cavity which is formed with at least one, but preferably a plurality, of elongated projections or shoulders which extend into said cavity, and which upon rotating the socket are intended to partially penetrate into the damaged bolt head and thus provide a driving connection therebetween to thereby provide torque to said bolt to thus cause its removal. If desired, the user may strike the means for rotating the socket to embed the projections or shoulders into the bolt head.
