One Wrench Size, Two Head Styles The double box ends are the same size and both are 12-point, but one side features a raised fixed head while the other has a ratcheting flex head Versatile Fixed Head The fixed box end has a flush side to maximize surface contact with a fastener as well as a raised side for finger clearance and to fit into recessed areas Ratcheting Flex Head The ratcheting end reduces the need to re-engage the fastener repeatedly, and the flex joint sweeps smoothly through 180 degrees without any set positions, allowing the wrench to access fasteners around obstacles Clear Markings Tekton fixed/flex head ratcheting wrenches are permanently marked in two ways: a high-visibility laser marking and a stamped marking Materials and Finish These wrenches are made from 6140 Cr-V steel, heat-treated to 4249 HRC, abrasive-blasted for a finely textured finish, and plated with a trivalent chrome process
Tekton Long Fixed/Flex Head 12-Point Ratcheting Box End Wrenches each have one wrench size and two head styles. The double box ends are the same size and both are 12-point, but one side features a raised fixed head while the other has a ratcheting flex head. The fixed box end has a flush side to maximize surface contact with a fastener as well as a raised side for finger clearance and to fit into recessed areas. The ratcheting end reduces the need to re-engage the fastener repeatedly. The flex joint sweeps smoothly through 180 degrees without any set positions, allowing the wrench to access fasteners around obstacles. The 12-point box ends fit multiple types of fasteners, including 6-point, 12-point, and square. Tekton fixed/flex head ratcheting wrenches are permanently marked in two ways: a high-visibility laser marking and a stamped marking. We make these wrench bodies from 6140 chromium-vanadium steel and heat-treat them to 4249 HRC. The wrenches are abrasive-blasted to create a finely textured finish and then plated with a trivalent chrome process.
