The 33mm Truck Lug Nut Installer and Remover, No. 13550, from Lisle Corporation, is a two-piece hex and twist socket set used for the installation and removal of normal, damaged, or corroded lug nuts found on some Class 6 and 7 and most Class 8 trucks. The left-hand twist socket has a sharp edge that firmly bites into stripped nuts. A 6-point hex socket grips fasteners without damaging or rounding. Sockets are impact-rated and made from chrome moly steel, with a 3/4" square drive.
