Glow Plug Thread Repair Kit M8 x 1.0 12mm for Diesel Engines

A glow plug thread repair kit for restoring damaged M8 x 1.0 threads on diesel engines. Used where glow plug threads have been cross-threaded or over-tightened, it helps put a usable thread back into the cylinder head so the glow plug can seat properly again.

Useful for mechanics, garages and anyone carrying out diesel engine servicing or repair work. When a glow plug change reveals damaged threads, a glow plug repair kit like this can help avoid a much bigger repair and get the job moving again. Commonly used on alloy cylinder heads, it suits workshop use, vehicle maintenance and engine repair where a worn or damaged glow plug fitting needs sorting out cleanly.

This thread repair insert kit includes a threaded tap, assembly tool and five 12mm deep coil inserts for M8 x 1.0 glow plug threads. The inserts are made from carbon steel and finished in black phosphate. That gives you the key parts needed for thread restoration when the original thread has been compromised. The insert depth is clearly suited to the stated application, and having multiple inserts in the kit is useful for regular maintenance or when working on more than one damaged thread.
