The exclusive Malco C-RHEX Cleanable-Reversible Magnetic Hex Chuck Driver, has become an indispensable accessory for HVAC and service pros. The unique, patented C-RHEX design ensures that popular 1/4 and 5/16-inch hex drives are just a flip away. The double ended hex socket barrel is quickly reversible and securely locks on the driver shaft in either direction without disengaging from the drill or impact driver chuck. The fully accessible magnet tipped shaft is easily cleaned with the swipe of a cloth or glove to avoid build-up of metal shavings in the hex opening. Tested torque is equal to one-piece single size drivers. The Malco C-RHEX completes the perfect metal fastening system when paired with Malco Zip-in and Bit-Tip screws. Optimum Zip-in and Bit-Tip head heights perfectly engage in the C-RHEX driver so that the hex washer screw head is always held flush for faster, more consistent fastening without risk of damage to the driver magnet. The C-RHEX internally seats the outer rim of the Zip-in or Bit-Tip recessed head to avoid direct contact with the powerful magnet.
