This professional ICON® Modular General Service Socket Set offers the versatility you need for the garage or jobsite. The ratchet has a 90-tooth gear mechanism for a tight 4° arc swing, ideal for work in confined spaces. The low-profile ratchet head makes it easier to work in tight, cramped engine bays. Each extension has a small diameter shank with knurling for a secure grip. The precision-machined gears deliver smooth ratcheting action and stand up to heavy torque. This tool-truck quality set includes a premium storage tray with three dual-color foam inserts for versatile organization. Like all ICON® hand tools, this set is backed by a hassle-free, manufacturer’s lifetime warranty.
