Knock sensor socket (For 24 mm hexagons only)

●Easy to position by touch with its 60 mm overall-length design

Its short, compact overall length of 60 mm makes it easy to handle in tight spaces deep inside the engine compartment. Even where visibility is poor, it can be quickly and easily fitted onto the sensor head by touch.

●Versatile operation in 2 ways. The drive end has a conventional 9.5sq. (3/8-inch) square hole, while the base of the socket itself is a 19 mm hex. Besides using a ratchet handle, you can turn it from the side with a 19 mm ring spanner or flat ratchet wrench in narrow gaps.
