Review on TIME-SERT M10 X 1.50 Metric Thread Repair Kit 1015: Reliable Solution for Thread Repair by Dylan Hohd

Repaired some severed engine mount bolt threads, saving my aluminum engine block. The kit is not cheap but orders of magnitude better than spiral inserts as it is a strong steel insert with rigidity. The repair is likely to be stronger than the stock threads as the block is aluminum and the aluminum threads in the block are now basically a bolt size larger. An optional tap guide is highly recommended when doing field repairs without a router or drill press to get the tap started straight.
