Spark Plug Thread Repair Kit 10mm Re-Thread Tap & 4 Inserts

This spark plug thread repair kit is used for cleaning up and restoring damaged 10mm spark plug threads in the cylinder head. It includes a re-thread tap and four inserts, giving you the main parts needed to repair worn or crossed spark plug ports without replacing larger components. It is a practical option when an existing thread needs attention and you want to restore a usable fixing point for the spark plug.

Suitable for engine servicing, vehicle maintenance and repair work where a spark plug thread has been damaged through wear, over-tightening or incorrect fitting. It is useful for garage jobs, workshop use and home mechanics working on petrol engines, especially when a plug hole needs to be brought back into service. Keeping a kit like this to hand can save time during inspection and repair work, particularly when thread damage is only discovered once the plug has been removed.

The kit is based around a 10mm spark plug application and includes four insert lengths: 3/8in, 7/16in, 1/2in and 3/4in. This gives you options when dealing with different thread depths in the cylinder head. The supplied tap is used to clean and re-thread the spark plug port before fitting the insert, helping prepare the damaged hole for repair. Having several insert sizes in one set also makes it easier to keep common repair parts together in the toolbox or workshop, ready for repeated servicing jobs without having to source each size separately.
