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 long does it take for a helicoil thread to cool off?
Give the metal about 15-30 minutes to cool off. To finish, simply use a wrench and back out the steel bolt from the hole. That’s how you repair a thread faster and stronger than a Helicoil thread repair.
How long does it take to cool a steel bolt?
Bring the temperature of the steel bolt up to 750 degrees or above and drop the bolt into the hole. Give the metal about 15-30 minutes to cool off.
Is the HTS-2000 easier to use than the Helicoil?
What’s more, when compared with Helicoil, our HTS-2000 is easier to use and has far-reaching automotive, military, aerospace and industrial application. Plus, unlike Helicoil, there are no taps, inserts, gages and tang break-off tools to worry about at all. All you will need is an oversized drill to drill the hole.
Do you need flux for HTS-2000?
The HTS-2000 high-tech brazing rod doesn’t need any flux, ends up tougher than the base metal and melts 500 degrees below aluminum. You won’t be needing any welding machine. Just a butane, propane, mapp or oxy-acetylene torch will be enough. All in all, you don’t have to be a professional to use this second-generation brazing rod.

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.
Can you have a thread failure in the same hole again?
Done right, you’ll never have a thread failure in the same hole again.
Is stripper thread more common than ever?
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.
