Thread Repair Tap M14x1.5 Exhaust Sensor NOX DPF Guide Bolt

A thread repair tap for recutting damaged M14 x 1.5 exhaust sensor threads, supplied with a guide bolt to help start the tap in the correct position. Built for NOX and DPF sensor fittings, it is especially useful where rust, heat and corrosion have left the original threads worn or difficult to reuse.

Used for exhaust repairs where replacing the full component may not be necessary, this tool helps restore threads so sensors can seat correctly again. It suits garage work, workshop servicing and vehicle maintenance, particularly when working around underbody pipework or in cramped areas where a standard tap can be awkward to line up. For mechanics and anyone dealing with seized or damaged exhaust probe threads, the guide bolt makes the job more controlled when access is restricted.

The short body is a practical advantage when space around the sensor fitting is limited, helping with access in tighter engine bay and exhaust positions. Six cutting edges help the tap stay centred as the cut begins, while the cleaning grooves in the guide bolt help clear dirt and corrosion during use. An external hex drive gives a more positive way to turn the tap when threads are stubborn. As it is made specifically for recutting damaged threads rather than cutting new ones, it is a sensible tool to keep ready for regular exhaust sensor maintenance.
