ABSTRACT:
This disclosure is directed to the use of an adjustable hand tool which employs means to prevent the separation of the cross members. Specifically the invention uses an arcquate circular cross section rib which selectively engages one of several arcquate circular cross sectioned grooves. The pliers further have a pin with a cap at one end and externally threaded at the other. The pin has internal threads with a securing screw threadably mounted therein. A threaded cap is threadably attached to the pin and the securing screw tightened against the cap to cause it to remain in its selected position.
