GearWrench 85578 9/16 Inch 72-Tooth Ratcheting Combination Wrench

The GearWrench 85578 is a 9/16 inch ratcheting combination wrench that combines the speed of a ratchet with the accessibility of an open-end wrench. This innovative tool features a 72-tooth ratcheting mechanism that requires only 5° of arc swing to move a fastener, compared to 30° for standard box-end wrenches, making it ideal for tight spaces and restricted access areas.

Key Features:

• 72-tooth ratcheting mechanism with 5° swing arc for maximum efficiency in confined spaces
• Patented open-end ratcheting design allows continuous rotation without removing wrench from fastener
• Surface Drive® Plus technology provides stronger grip and up to 25% more torque with reduced fastener rounding
• 12-point box end for secure engagement with hex fasteners
• Extended beam length provides greater leverage for improved torque application
• 9/16 inch size fits standard SAE fasteners

Specifications:

• Overall length: 7.504 inches
• Open end width: 1.152 inches
• Open end thickness: 0.307 inches
• Box end width: 1.020 inches
• Box end thickness: 0.354 inches

This professional-grade wrench is engineered for mechanics and technicians who demand productivity and reliability. The ratcheting function eliminates the need to reposition the wrench between turns, dramatically reducing work time on repetitive fastening tasks.
