The Matco Inverted Torx Impact Socket Set is a high-quality hand tool designed specifically for automotive use. This single item set includes sockets in sizes ranging from E5 to E16, all with a 3/8″ drive size. The specialty impact sockets are made with black oxide finish for durability and are designed to provide a secure grip on nuts and bolts. This is a used set, however they were purchased shortly before I retired, so they weren’t used much. Some of them have never been used.
