Quickly change between 1/4 in and 5/16 in hex sizes with Malco®'s unique, exclusive, dual-sided magnetic hex drivers. The reversible hex socket fits over a 1/4 in magnet-tipped, ball locking hex shaft and can be quickly reversed to change sizes. Eliminate troublesome buildup of metal shavings in the hex tip with the "easy clean magnet". Just swipe with a glove or shop towel to clear any metal shavings. Tested torque of the reversible hex chuck driver design is equal to one piece drivers.
