Genius Tools Spark Plug Sockets 3/8" Dr.
Genius Tools Spark Plug Sockets 3/8 inch Dr. are dedicated sockets for removing and installing spark plugs with a 3/8 inch drive ratchet or extension. Their depth clears the plug's ceramic insulator so the socket can seat fully on the hex.
The series has three sizes. The 14mm socket has a 12-point opening, while the 16mm (5/8 inch) and 20.6mm (13/16 inch) sockets have 6-point openings, which grip the flats of the plug hex firmly and help when a plug is tight. Each socket is 63mm long.
Having the correct spark plug socket helps avoid rounding the plug hex and makes regular tune-ups faster. Pair it with an extension when the plugs sit deep in the head.
These sockets are made of Chrome Vanadium Steel. They are a useful addition to any automotive or small-engine tool kit built around 3/8 inch drive. Choose the size that matches your plug hex, and keep a 3/8 inch drive extension nearby for plugs set deep in the cylinder head.
