Impact wrench - 1" square drive

The 1' square drive impact wrench is the largest sized impact wrench that we supply. This is a heavy-duty impact wrench that is designed to tackle the biggest wrenching jobs. This sized impact wrench may be found in a commercial vehicle garage, since it is capable of tightening and untightening large bolts. Specific impact sockets should only be used with impact wrenches, since normal sockets are not strong enough and may break.

• 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 your power source: 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
• Additionally there is often a choice between single, 2 or 3 speed gears. Most impact wrenches have a variable speed function.
