a wrench compatible for use in limited access areas is made up of two components . a socket with fluted interior walls cooperates with a handle assembly consisting of a head with complementary fluting on its exterior surface attached to one end of a shaft . the head is inserted into the top of the socket and the shaft is rotated as far as the available space permits . the handle assembly is then lifted upward until the head is separated from the socket , the shaft is thereafter returned to the starting point , the head returned to the socket and rotated again . these steps are repeated until the nut or bolt is tightened or removed . the interior fluting permits the rotation of the socket by small or large increments . additional embodiments include a spring loaded pin that connects the head of the handle assembly to the socket while assisting the head to be raised a sufficient distance for the head of the handle assembly to be rotated and reseated in the socket . additional sockets with lower portions having different interior diameters can be used with the same handle assembly for nuts and bolts of smaller and larger diameters . an auxiliary extender and an alternate handle assembly make tight or narrow areas more accessible .
