The GEARWRENCH 120XP™ mechanics tool sets feature our 120 tooth ratchets, that take access and speed to the next level, making it easier and quicker to complete jobs. The double stacked pawl design gives 120 positions which gives a 3 degree ratcheting arc. All of the ratchets feature a low profile head and flush mounted on/off switch, allowing better access in tight spaces. The ratchets have an enclosed head design which allows for extreme resistance to dirt infiltration. The GEARWRENCH sockets are made from chrome vanadium steel with a full polish chrome finish that is easy to clean and resists corrosion. The sockets feature larger, hard-stamped size markings, as well as, the double ring (SAE) and knurled ring (metric) for easy identification while on the job. They feature off-corner loading to reduce fastener rounding and the chamfered opening helps guide the socket on to the fastener. The 80550P is a 56 piece 3/8 In. drive set with a blow mold case for storage and portability.
