CONNEXT Quick Change handles from Malco, combined with precision-fit and hardened Malco Magnetic Hex Chuck Driver shaft components, offer the ultimate in Hex Hand Driver durability and flexibility. Hex Hand Drivers shown here are sold pre-assembled and packaged as one product, but components are also available separately. Replacing a worn hex hand driver with just a handle or driver shaft at a time is more economical. And changing a hand-held hex driver size can be as easy and thrifty as retrieving a different size chuck driver shaft from your tool box.
