A ball joint (42) is formed at the rear part of the head and a pin (46) passes transversally through the front part of the handle and through hole (44) of the joint. The through hole is larger in diameter than the pin so that the joint can be freely pivoted up and down and right and left and the handle can be freely pivoted relative to the head. When the handle is positioned at an end position of the swivel angle, the handle can be turned to turn the wrench. #CMT# : #/CMT# A spring member is placed in the indentation to elastically press on the joint. #CMT#USE : #/CMT# AS screw wrench #CMT#ADVANTAGE : #/CMT# Enables wrench to be used at any angle for inaccessible areas. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# Figure shows exploded view 30 : handle 42 : ball joint 46 : pin 44 : through hole.</p>
