Made for the ShaftLOK™ Driver, our patented locking shafts eliminate the danger and inconvenience of bits falling out of the shaft when getting partially stuck in the fastener.
Extension shafts lock into the ShaftLOK™ driver and provide a super slim profile for getting into tight and hard to reach places.
ShaftLOK™ extensions have a 0.375" (9.6mm) minimum clearance, and you can link multiple extensions together for that extra long reach.
