Marketing InformationCONNEXT® quick-change handles from Malco®, combined with precision fit and hardened Malco® magnetic hex chuck driver shaft components, offer the ultimate Inch 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 bag.
