This invention is a cam actuator means with connector assembly with one embodiment being a stud extractor and wrench apparatus operable to utilize a cam insert member mounted within an outer housing member being engagable with a damaged bolt head on a stud member using a cam actuator clamping action to grasp same for inserting and removing. A second embodiment is a main brake lock apparatus having a brake insert member mounted within an outer brake housing member being engagable with a rotating shaft to achieve a braking or clutching action therewith through a cam actuator clamping action. The brake actuator assembly uses a piston and cylinder actuator assembly selectively operable through fluid control means to contact and engage the shaft for the braking or clutching action. A third embodiment is a bolt and elliptical lock nut apparatus having an inner lock cam insert member mounted within a main lock nut assembly. The inner lock cam insert member is engageable with a threaded bolt member at any longitudinal position being operable through relative rotational movement between the main lock nut assembly and the inner lock cam insert member to a achieve a cam actuator clamping action on a threaded body section of the bolt member.

This invention relates to a stud extractor and wrench apparatus using a cam action locking feature to grasp a stud member or bolt head member for removing same. The stud extractor and wrench apparatus includes a main cam lock assembly driven through a main drive assembly. The main drive assembly can utilize a conventional ratchet drive assembly or can take the form of a box end wrench drive assembly. The main cam lock assembly includes an outer housing member having mounted therewithin a cam insert member. The outer housing member has an elliptical cavity opening with an inner cam surface and a wrench head section. The wrench head section resembles a standard socket wrench member which is engagable with the ratchet drive assembly for rotating in selected opposite directions. The cam insert member can be releasably mounted within the outer housing member and includes an elliptical cam body. The elliptical cam body has a central serrated opening to receive and engage the stud member or bolt head member during a removal operation.
