12 Pt Fractional Box End Wrench Set - 5 Piece

  • Made in the U.S.A., featuring quality workmanship and value.
  • The patented SureGrip® hex design drives the side of the fastener, not the corner. This not only provides increased strength, but also avoids the rounding of rusted or damaged fasteners, which can occur when using a sharp cornered hex tool.
  • Box ends are offset for improved hand clearance in tight workspaces.
  • S•K wrenches are unconditionally guaranteed against defects in materials and workmanship for the life of the tool.

    5 Piece Set Includes:
  • 3/8" x 7/16" Wrench
  • 1/2" x 9/16" Wrench
  • 9/16" x 5/8" Wrench
  • 11/16" x 3/4" Wrench
  • 13/16" x 7/8" Wrench
  • Packaged in a roll.


  • Caution: Do not use pipes or other extensions to increase leverage on the wrench. Such use damages the tool, and may also result in bodily injury.
