The Sunex Tools 42-pc 3/8" Drive Chrome Socket Set, No. 3842, features high visibility red and blue markings that are laser etched before the chrome process, making the sockets resistant to abrasion and corrosion. The markings allow for easy and fast identification of each socket. The sockets have a radiused corner design that allows for almost total torque to the flat of the fastener instead of the corners. The sockets also feature chamfered ends that quickly guides the fastener into the socket. The set includes a 80-tooth low profile ratchet for access into tight areas by providing a smaller arc swing during rotation.
