Can you fix damaged threads?
Damaged threads on a screw or bolt can often be fixed by running a die over it, and if a thread's damage is minimal, it may be possible to reform the threads by running a nut up and down them, though that runs the risk of the nut fusing to the thread (galling).
What is used to repair damaged threads?
A cutting die cuts new threads, whereas a rethreading die is like a thread chaser to fix slightly damaged or dirty threads. Some cutting dies are split with a set screw to adjust the size of the cut for minor variations on diameter. Most hobbyist-type kits use solid dies.

How to repair M10x1.25 thread?
For an M10x1.25 thread repair with a Keensert, a 12.5mm drill would be used for the M14x1.5 tap. The M14x1.5 tap would have a major diameter up to 14.4mm (an M10 repair with an S.T.I. tap would only have a 11.787mm major diameter). That’s a much bigger hole which can be beneficial in some application where severe corrosion is prevalent in the original threads. The Keensert would then be threaded into the drilled, tapped and cleaned hole with the Keensert installation tool. Thread locking compounds can be used due to its solid body design. Once set in position, the installation tool is then used to drive in the four key stakes into position. This provides the ultimate mechanical locking of the insert in place. Hence, this design sports exceptional resistance to vibration. Now the downside. The massive outside diameter of the insert makes it unviable in applications where the material around the original threaded hole is limited, such as any “thin-wall” castings. Second, the cost for a standard-steel Keensert is about 4.5 times that of a HeliCoil and more than double the cost of a TIME-SERT. If you want a stainless-steel Keensert, the cost goes through the roof being about 25 times the cost of a HeliCoil.
How hard is it to drill a stripped hole?
How easy or how hard usually depends on the access to the stripped hole. If you can take off the entire header and get enough access to fit a cordless drill in the area to drill out the hole before tapping, it pretty easy. I;'m guessing it would probably be an M8x1.25 thread. Compare the size and thread on one of the good bolts to a know M8x1.25 bolt to confirm.

Can Keensert be threaded?

Can you fix threads?
There are many not so ideal ways of fixing damaged threads by way of oversizing and cross threading; but what a lot of people don’t know is that there are many engineered solutions to properly fixing damaged threads.

Do self tapping inserts require a pretapped hole?
