Providing Quality Tools Since 1907. Essential tools for your home, Auto,
and Office ProjectsCooper Hand Tools designed this set to meet or beat the standards set by competitors such as Snap-on, Craftsman, Husky and Stanley.
Every piece in this set exceeds the standards set by the American Society of Mechanical Engineers.
The Ratchet drive has a mechanism that locks sockets to it so that they will not inadvertantly slip off.
The sockets, ratchets, nut drivers and bits are made with chrome vanadium, an alloy that is added to carbon steel to give the set increased strength and durability.
