Glow Plug Thread Repair Kit M10 x 1.0 Diesel Cylinder Head

A glow plug thread repair kit for restoring damaged M10 x 1.0 threads in diesel engine alloy cylinder heads. Used when threads have been cross-threaded or over-tightened, it gives you the parts needed to put the thread right and get the glow plug seating properly again.

Used in engine repair, workshop servicing and vehicle maintenance, this kit suits mechanics dealing with worn or damaged glow plug holes on diesel engines. It is a practical option when a proper thread repair is needed rather than a temporary fix, helping avoid a larger repair job if the original thread has failed. For garage work or regular servicing, this thread repair insert kit is useful to keep close to hand when common cylinder head thread problems come up.

The kit includes a threaded tap, assembly tool and coil inserts to help restore a straight, usable thread for refitting the glow plug. Two insert depths are supplied, with 5 x 12mm inserts and 5 x 19mm inserts, giving more flexibility depending on the depth needed for the job. The parts have a black phosphate finish for practical workshop use. Having both insert depths in one kit helps cover common repair situations and makes it more useful for repeated maintenance work on diesel heads.
