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.
