How does helicoil stay in place?
The HeliCoil insert itself has special threads designed to grab the walls of the part, and the tang is there to help drive the insert into place. Free running inserts are fully rounded inserts that are slightly larger than the hole they install in.
What is the difference between insert and helicoil?
Unlike helicoils which have a slim profile, inserts are extremely large and require a large external thread for installation. The second most common flaw is the removal process. Removal requires drilling out material, bending the key insert and utilizing a screw extractor to remove the insert.

How do you fix a stripped thread?
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.
Which is better HeliCoil or Time-Sert?
After doing a bit of research it sure seems to me that the Time-Sert is the clear choice for a more full-proof 'permanent" fix. The only advantage to a Helicoil I found, is that it is cheaper. Being in the industry for a little while I have seen time and time again, that cheaper is never better.

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.
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 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.
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.
Can Keensert be threaded?
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.
Where to thread Helicoil insert?

What is heli coil insert?
HeliCoil® inserts are small, sometimes underappreciated, fastener components that are integral for reinforcing a stripped thread. The HeliCoil instructions below will help you learn what a HeliCoil is, their applications, and how the threaded inserts are installed.
What are HeliCoils?
A HeliCoil, otherwise known as a screw thread insert or helical insert, is a registered trademark of STANLEY Engineered Fastening. It has a stainless steel wire that has a diamond-shaped cross-section and repairs stripped thread in hard metals such as steel or soft materials such as wood or plastic. HeliCoils create stronger bonds than the original fastener because they are coiled wire inserts that are wider than the tapped hole. When you insert them into the hole, and as you screw the bolt down, the coil tightens and creates a seal. As a result, these inserts prevent wear while boosting the integrity and lifespan of its application.
How to repair threads in aluminum?
Drill out the old threads by selecting the recommended drill size from the thread repair kit packaging. If drilling in aluminum or hard metals, apply cutting fluid to the drill bit and the hole throughout the drilling process to prevent the drill from clogging.

What is a thread repair insert?
Thread repair inserts, allow for threads to be repaired, recreated, or reinforced to the original bolt size and pitch. Solid inserts which are often made of stainless steel or carbon steel, can not only be used to repair damaged threads but also to reinforce soft base metals like aluminum to be able to take a much higher torque.
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. Even more problematic is that most people are only aware of coil based repair kits (like helicoil or permacoil).
Do self tapping inserts require a pretapped hole?
Self tapping (gardsert/seal-lock/ensat) Installation: The easiest method of all, these types of inserts do not require a pretapped hole, as they create their own threads as they are installed. They also do not require special installation tools and utilize a normal nut and bolt for installation.
