Abn Spark Plug Thread Repair Rethreading Set 14mm Metric Rethreading Tool Kit Comprehensive Taps - Shop Hardware Tools Online Store

Fix a stripped spark plug threaded port with the ABN Spark Plug Thread Repair Rethreading Set. The 14mm thread size is suitable for damaged spark plug threads with either a tapered seat or a gasket seal type spark plug assembly. The stepped tap ensures correct alignment of the cutter in an existing spark plug hole, and the extension tools allow easy access to the bottom of the plug recess (includes plug inserts). If you are performing this fix without removing the head from the vehicle, you may not have enough room to use the expander effectively. Cut a larger threaded hole in the cylinder head with the tap, screw the insert into the head, screw the plug into the insert, and use the expander to seat the insert.
