How do you fix a stripped thread hole?
The complete repair for stripped threads is to use a coil-type thread insert. These inserts will give the bolt hole completely new threads which accept the size of the original bolt. In order to use inserts, you must drill the damaged holes slightly larger so that it can take the thread insert.

What is a helicoil thread?
If neither of the options above are doing it for you can use a Helicoil. A Helicoil is a coil wired thread insert. The coil replaces the original threads. Essentially you drill out the hole with the correct bit size. You can then tap the hole and insert the coil. After the coil is inserted you then bust off the tang.
Why do bolts lose their strength?
Over time bolt s and threads sometimes lose their strength. Due to friction or corrosion, the threads can deteriorate. Having these weak threads can prevent you from being able to tighten down a bolt. The first option is looking at the bolt hole. If you have some extra distance that the bolt doesn’t cover you may be able to use a longer bolt. If there are some decent threads that your longer bolt can reach you may be able to tighten it down.
Can you drill a hole in a bolt?
If most of the threads have been a victim of damage you may be able to increase the size of the hole. As long as there is enough room on the outside you may be able to drill out a larger hole. This will allow you to rethread the hole and give you the ability to use a larger bolt.
How to repair a stripped thread?
Similarly, when threads are stripped out of a hole, there are a number of approaches one can take to repair them. Drilling out the hole and tapping it with a larger diameter thread is one option, provided there is room for a larger fastener. When creating a new, larger tapped hole isn't optimal or possible, use of a thread repair kit is recommended.

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.
What is thread repair insert?
Thread-repair inserts come in a variety of materials and in a myriad of designs from domestic and overseas manufacturers. Timed thread body inserts, wire coil inserts and keyed inserted make up the three major families of thread inserts you’ll likely encounter.
What size drill do I use for a M10x1.25?
First, you would drill the hole with a 10.25mm drill (a standard M10x1.25 thread would use a much smaller 8.75mm drill). Then you would use an M10x1.25-S.T.I. tap. This S.T.I. version of the tap will have a major diameter of up to 11.787mm, whereas a standard M10x1.25 tap is about 1.5mm less in diameter.
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.
What is the hardness of cast aluminum?
The highest hardness cast-aluminum alloys are used in block and cylinder heads. These will typically have a range of hardness from 75-to-85, about the same as 6061-T6. Only 7075-T6 aluminum alloy has a hardness of 150 which is on par with grey cast iron.

As a result, it’s no surprise that strippers are more common than ever before. Since most of the threads on today’s vehicles are made of materials with just one-third to one-half the hardness of grey cast iron, it’s no wonder that more threaded holes experience thread damage than ever before.
Can you use timeserts on aluminum heads?
I use only timeserts as well and have never had any problem with them. Do them all by hand (spark plugs that is). I use the aluminum insert on aluminum heads.
Can I use time-serts on spark plugs?
Same as Mike, I only use time-serts for spark plug thread repair. I install them by hand or with the machine doesn't really matter either way as the tools are guided. I wipe a film of "Fluid-weld" on the insert to help with heat transfer and give it that extra bit of "lock".
