The Reversible Ratcheting Combination Wrench Set features popular wrench sizes with a full polish chrome finish for durability. The wrenches feature a reversing lever to quickly change the direction of the wrench. The box end utilizes Surface Drive technology which provides off-corner loading for better grip and reduced fastener rounding. 72-tooth ratcheting box end needs a minimal 5° to move fasteners vs. 30° for standard wrenches. Flush mounted reversing lever allows you to change direction without removing the wrench. Off-corner loading design on box end provides better grip and reduces fastener rounding.
