The set comes equipped with a 90-Tooth quick-release ratchet as well as a universal joint, power socket adapter, and extensionwhich arent often found in most sets. All of the tools come stored in a sturdy carrying case. The 6-point socket openings are ideal for working with hex-shaped fasteners and designed to grip the sides and not the corners of the fastener heads, preventing round-off. An extended length allows the deep socket to fit over long fasteners and reach into recessed areas. The large, die-stamped markings are permanently impressed into the material and optimized for readability. A mirror chrome-plated finish protects against corrosion and easily wipes clean.
