• 72-Tooth Reversible Ratcheting Mechanism: The internal ratcheting gear utilizes a 72-tooth architecture that achieves a minimal 5-degree swing arc. This allows you to rapidly spin fasteners in exceptionally tight quarters where standard combination wrenches cannot clear a functional swing radius.
• Dual Reversing Switch Levers: Equipped with a premium chrome-vanadium quick-change lever integrated directly into the head. This allows you to instantly toggle the ratcheting direction from tightening to loosening with one hand without lifting the tool off the fastener.
• TorquePlus™ 12-Point Box End: The box end is machined with Proto's proprietary TorquePlus™ drive system, which redistributes torque forces away from the vulnerable corners of the hex hardware and onto the stronger flat sides. Its 12-point configuration allows for effortless self-alignment over 4-, 6-, and 12-point fasteners.
• Anti-Slip Design (ASD) Open End: The open-jaw end features patented geometric locking grooves that bite securely into the sides of a bolt head. This design provides supreme grip under high torque loads and keeps the wrench from dangerously slipping or sliding off the hardware.
