Cleco Nutrunners


How to Select Your Cleco Nutrunner...

Cleco offers over 500 varieties of nutrunners most of which can be equipped with different final drive options (hex, crow's foot, Keller wrench, etc.). This in turn generates over 3,000 different nutrunner combinations, allowing the exact tool to be built according to the needs of a specific application.

Before selelecting a tool for any assembly application, the following factors should be taken into consideration:

  1. Operator ergonomics involved with the process (man | tool | task relationship)
  2. Torque and speed requirements
  3. Accessibility to the fastener (resticted area or open space)
  4. Joint variations (soft vs. hard)
  5. Operator experience level and ability
  6. Air supply to the production line
