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

TEKTON 21 mm Long Fixed/Flex Head 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
