Oxygen Sensor Thread Tap M18 x 1.5 Guide Bolt Short Body

An oxygen sensor thread tap used for cleaning up and recutting damaged sensor threads on exhaust fittings. The M18 x 1.5 size suits oxygen sensor, NOX and particle filter sensor thread repair, while the short body helps where space is limited around pipes, housings and underbody components.

Used for exhaust repair, vehicle maintenance and workshop servicing where sensor threads have become rusted, worn or difficult to reuse. It is particularly useful for garages, mobile mechanics and anyone carrying out repairs on awkwardly positioned sensors, especially when seized fittings or restricted access can turn a simple sensor replacement into a longer job.

The guide bolt helps the tap start more accurately in the existing thread, which is important when trying to recover a damaged fitting rather than replace the whole section. A short pattern makes it easier to work in tighter areas under the vehicle or close to surrounding parts. The 6 cutting edges support better centring as the thread is recut, and the cleaning grooves in the guide bolt help clear debris during use. An external hex drive gives a more secure way to apply force than trying to manage the tool by hand alone, which is useful for regular exhaust and sensor maintenance work.
