3/8' square drive impact wrenches are used to tighten and untighten bolts. This is a small sized impact wrench which is designed for lighter duty work. Our 3/8” impact drivers are cordless, which improves overall convenience. When choosing an impact wrench the size of the square drive is one of the main considerations, since the larger the size, the bigger the sockets it can support. Impact sockets should be used with impact wrenches.

  • The key consideration when choosing between impact wrenches is the size of the hex drive (measured A/F or 'across flats') to suit increasingly larger sockets for increasingly larger nuts & bolts.
  • Choosing the right battery: Cordless (or battery powered) tools have a variety of chemical battery types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
  • Additionally there is often a choice between single, 2 or 3 speed gears. Most impact wrenches have a variable speed function.
