Reversible Ratcheting Combination Wrench Set, SAE – 9509N. 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. The GEARWRENCH ratcheting wrenches use as little as 5° on the box end to move fasteners versus 30° for standard wrenches. The flush mounted reversing lever on the GEARWRENCH wrenches allow you to switch directions without needing to remove your wrench from the fastener. Our pass-through technology allows for fitting the ratcheting box end down over long threaded rods. The off-corner loading design of the GEARWRENCH ratcheting wrenches provides a stronger grip on fasteners, as well as, reduces fastener rounding.
