The OEM Automotive Tools 121-pc Mechanic's Tool Set includes a variety of the popular size sockets, wrenches, screwdrivers and other tools. Most of the items feature a hard chrome finish, which won't show prints and keeps rust away. The pliers have precision machined jaws and feature TechReady grips that reduce hand fatigue, according to the company. The set includes a ratcheting screwdriver with 45 teeth and three locking positions for smoother strokes. The sockets are designed with thin walls and chamfered ends and feature Posi-Grip no slip design with off-corner loading for greater torque and more socket-to-fastener contact. The set comes in a blow molded case.
