The Harbor Freight Icon 3/8" Drive 54-pc SAE and Metric Modular General Service Socket Set, No. 70469, includes a premium ratchet with a 90-tooth gear mechanism for a tight 4-degree arc swing. The ratchet features a low-profile head for use in cramped engine bays, and precision-machined gears deliver smooth ratcheting through daily use. The thin-walled sockets have chamfered openings for easy fastener and drive engagement and a shallow hex depth that keeps the fastener positioned near the end of deep sockets. The ratchet and sockets have a polished chrome finish for corrosion resistance, and the set comes in a carry case with modular EVA inserts for toolbox storage. All of the tools are backed by a lifetime warranty.
