GEARWRENCH mechanics tools have all been designed with the professional user in mind to increase productivity, access, and strength. The 120 tooth ratchets and sockets are made from premium alloy steel and feature a full polish chrome finish that resists rust and corrosion. Large, hard-stamped markings allow for easy identification and can be easily recognized as SAE (double line) or metric (knurled line). Additionally, the off-corner loading design puts force on the flats of fasteners for improved durability and reduced fastener rounding. 120XPT ratchets have two double stacked 60-tooth pawls (120 positions) providing a 3° swing arc so you can turn fasteners in tighter confines. Double-stacked pawls alternately engage the 60-tooth gear, providing exceptional strength. Sockets feature off-corner loading design reduces fastener rounding. Extension bars features a knurled grip, providing a non slip surface. Bright, full polish chrome finish easily wipes clean and resists corrosion. Hard stamped size markings. Includes blow mold case for storage and organization. Meets or exceeds ASME specifications.
