Hyper Tough 3-Piece Spark Plug Sockets (Model 1202) provide three spark plug sockets, 5/8", 3/4", and 13/16" to ensure you always have the standard spark plug sizes. These spark plug sockets conveniently fit with your standard 3/8" Ratchet Drive. These spark plug sockets feature a rubber gasket inserted into the socket to hold the spark plug securely into place and 6 point ends to prevent round-off. They are designed with a corrosion-resistant finish and are heat treated so they last as long as you need them to.  An interior rubber grommet firmly grips the neck of plugs for careful removal and installation. Advanced design grips flat sides of hex nut, not corners. With Hyper Tough 3-Piece Spark Plug Sockets, you have the right size of socket whenever you need it.
