TEKTON 21 mm Long Fixed/Flex Head 12-Point Ratcheting Box End Wrench | WRB35421

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 42-49 HRC, abrasive-blasted for a finely textured finish, and plated with a trivalent chrome process
