Abstract

An open ended ratchet drive socket wrench (10) and different sized drive sockets (34, 34'"'"') provide for connecting and disconnecting nuts of different diameters to studs of different diameters and lengths; each of the drive sockets has a hexagonal fitting (40, 40'"'"') on one end that extends outwardly of the head of the wrench for providing clearance between the workpiece and the wrench and to connect to a nut on a stud and wherein each of the different sized sockets has a connector end (35, 35") on the opposite end thereof that extends through the head for connection thereto and for ratchet drive thereby and wherein the connector end (35, 35'"'"') has an opening (40a, 40a'"'"') therethrough that will clear stud sizes for nuts tightened thereby and the single open ended socket wrench has a stepped bushing that will universally accommodate different sized hexagonal fittings.

Claims

1. A tool kit including different sized open ended drive sockets, an extension adapter and an open ended socket wrench with a handle and a head with a bore therethrough:

said head having a stepped bushing with end portions fit in and extending through said bore and including a center head opening with a head drive tooth connected to said stepped bushing and extending radially into said center head opening;

each of said different sized open ended drive sockets being selectively connectable to said head by each of different sized open ended drive sockets having a driven connector end including a slot that receives said head drive tooth for interlocking said driven connector end to said head drive tooth;

said different sized open ended drive sockets each having an opening for passage of a threaded member therethrough;

said extension adapter having an adapter connector end with a slot having the same configuration as said slot on each of said different sized open ended drive sockets and said slot on said adapter connector end engageable by said head drive tooth for interlocking said extension adapter to said head drive tooth;

said adapter connector end slot selectively engageable with said head drive tooth when said different sized open ended drive sockets are disconnected therefrom;

said extension adapter having an opening for passage of a threaded member through said extension adapter and said head;

said extension adapter having an adapter drive end;

said adapter drive end having an adapter drive opening therein and an adapter drive tooth;

said adapter drive opening and said adapter drive tooth having the same configuration as said head opening and said head drive tooth;

said adapter connector end on said extension adapter and said driven connector ends on said different sized open ended drive sockets having the same configuration for being universally selectively engageable by said head drive tooth and said driven connector ends on said different sized open ended drive sockets further being selectively engageable to said adapter drive end of said extension adapter when said adapter connector end of said extension adapter is engaged with said head drive tooth.
