CONNEXT® – Hollow Nut Drivers

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


  • Shock and shatter proof handles.
  • Quick connector mechanism for fast changes.
