• Convert your 1/2" square drive impact tool into a powerful 1/4" hex bit driver when extra torque is needed; such as driving extra-long deck screws, tightening anchor bolts or removing stuck fasteners
• The 1/4" drive works with any standard 1/4" hex shaft screw driver bit
• Positive locking quick change collar delivers wiggle free bit retention and solid on center rotation
• Constructed of chrome molybdenum steel for heavy-duty impact applications and long service life
