ABSTRACT:
The modular wrench with extendible shank includes at least one stubby wrench head segment having either an open end or a box end wrench head, and a truncated shank extending from the wrench head. A short connector sleeve having sockets defined in both ends that frictionally receive the truncated shank of the wrench head segment is provided so that two wrench heads may be attached to opposite ends of the sleeve to form an open end wrench, a box end wrench, or a combination wrench of standard size. Two elongated extension bars, e.g., a six-inch and a ten-inch bar, are provided, each extension bar having a stub projecting from one end that frictionally fits into the connector sleeve, and a socket defined in the opposite end that frictionally receives either the truncated shank of the wrench head or the stub of the other extension bar.
