TEKTON Long Flex Ratcheting Wrench

Extra Length

The extra-long beam offers extended reach into narrow spots and increased leverage for turning tough fasteners.

180° Flex Heads

The flex heads sweep smoothly through 180 degrees without any set positions. This allows the wrench to ratchet freely at any angle and navigate around obstructions in its swing path.

TEKTON Flex Ratcheting Wrench with 6-point box ends

6-Point Box Ends

  • The 6-point box ends provide an exact fit and maximum contact for hex fasteners.
  • To prevent rounding off fasteners, the box ends are designed to grip and apply force to the flat sides of fastener heads, rather than the corners.

Reach Over Long Fasteners

Slip the box ends over long threads to quickly ratchet fasteners that you can't reach with other tools.

72-Tooth = 5° Swing Arc

  • The 72-tooth ratchet gear requires only 5 degrees of swing arc to reach its next tooth position, making it ideal for working in tight spaces.
  • The ratchet gear is cut, rather than press-formed, to create precise teeth that fully engage with the pawl and won't slip under high stress.

Included Wrench Holder

  • The wrench holder's flexible teeth grip the wrenches and hold them in place, even while you're on-the-go.
  • Fold down the wrench holder's handle to save space when storing it in your tool cabinet drawer.
