I know this is not the correct forum part to ask this.

The usage is.
LOCTITE-28654-Form-A-Thread-NEW-Henkel-Loctite-236382 !!
Apparently able to withstand 170lbs torque. (Not sure what size bolt)

The (possible) best solution to fix the ripped out threads without any additional tools needed!!!

I really like to try and inform you guys of the usability.

LOCTITE - 28654 Form-A-Thread - NEW Henkel Loctite 236382, PC 3967 79340286542 | eBay

www.ebay.com

For me (Thailand) that's +/-$20 for the product, + $30 for transport + $28 for pre-paid tax...

Or buy local webshop for +/- 6000 THB ($192,-) (still shipped from USA)

As you can understand, absurd for a product for $10-25 (I can find different suppliers online with different price range)

I paid one time $30 extra to get ox-gard, still absurd on $15 product price, but atleast it's a big tube.

Who can help me purchase and sent per express normal post to Thailand??
It's small and light, should fit in a normal envelope.

(Best via PM)

Naturally I can pay for the product and shipment via PayPal or so.

I have helicoil.
That repair isn't always successful for me

Next step is M8.
And those also aren't always the fix.

Then I can choose M8 helicoil, but kind of impossible to tap M9 in 6mm material.

I think it's a good alterative.

Probem is getting it for Thailand.

Anyone willing to help?

Those torque number are values of the bolt not the threaded hole.
It is based on the material and heat treatment condition they are in.

Please explain where you found this information.

The PDF states:
Maximal Torque value for repaired threads.

As they have absolutely no information about used bolts, how can they possibly provide any information about it??

Titanium M6 bolt...
Handles a lot more then 23.
Aluminium M6 bolt.
A lot less.

Always open to learn, but I don't see what you see how the information they write about repaired thread gives information about bolts.

I can't find what type of material that bolt you refer to is made of.

Please enlighten me :)

Ok, thank you.
Did either you use the product??

I'm not asking for alternative solutions.
I have probably more already available here at my home then you can think of.
That doesn't mean they work for me.
That's why I'm searching for alternative solution.
This seems like a valid one, where the reviews and YouTube video's arre really promising.

Really promising.

Am asking help acquiring this solution.
Not a different one.

I have several types of taps and thread Incerts.
Often work, not always.

This looks like a solution that will work always.

Also for my stripped M8.

If no one is willing or able to assist, I need to pay + $70 to acquire this.
Almost unobtainium.....
For Thailand that is.
USA, you get it at Walmart or so :)

In Your post it states Grade 5 which is used for inch sizes and Grade 8.8 which is used for metric sizes.
Below is a chart of the grade strength.
Aluminum depending on grade would be 1/4 as strong.
120,000/4 = 30,000 psi
That means you need to take the torque setting of a standard steel hardware and also divide it by 4.
It is why I recommend using Brass Set Screws.


J429 Mechanical Properties
GradeNominal Size, inchesTensile Strength, min, psi
2Over 3/4 thru 1-1/260,000
51/4 thru 1120,000
Over 1 thru 1-1/2105,000
81/4 thru 1-1/2150,000
 
I think I understand where your confusion comes from.

Yes, the pdf mentions 5 and 8.8

So it inform you about the maximal Torque used 5 / 8.8 bolts.

NOT the strength of the bolt itself
That can have way more then 170 Lbs, on larger bolt size :)

The 23Lbs, 30Nm for M6 / 1/4 inch is high.
Usually adviced in iron is 17Nm.
23lbs/30Nm is really strong.

We are talking about a thread repair product, not general strength of bolts and maximum torque.

The thread made with this product is supposed to able to withstand 30Nm on M6
And that is a lot.
Absurd high, I might say.

Without going too deep into this side discussion, I really like to TRY and not have theoretical discussions on how the manual needs to be interpreted.

I like to try if this is viable solution.
Thoughts about how it "can not be good" and "you should do or should not have done" aren't helpful.
Hands on experience is.

If you haven't used it, it's impossible to have valuable thought about it.
That it doesn't feel good, isn't fixing or replacing my threads.

This might.
The incerts might.
Going to M9 I really like to prevent.

How to get this unobtainium??
Who is willing to help?
 
Amazon..
The 12.9ml kit that costs about $28
Not kidding.
$360 - $360 shipping costs.

I know Thailand isn't really close but this is absurd.

Right - you need a $20 product, plus an affordable shipping via DHL etc to Thailand, and someone willing to post the package for you.

It's the plight a many a Ex-pat face.

I've never been to USA, so it's not about that.

It's strange how some products are USA only, and "impossible" to obtain in Asia.

One would think there local alternatives that do more or less the same.
While I'm able to find almost anything on internet, this is a big no.

Together with antioxidation compound like ox-gard..
Asians live without it.

I will offer to send whatever you want. I have experience filling out customs declaration forms, my wife is Ukrainian.

Yes it is a little effort, but I understand your frustration.
 
use jbweld. or metal putty. either one should be available at auto parts stores. or go to mechanic shop and ask for little bit

here's some examples. there should be something similar in thailand

I've done some more research and came across these videos:

The video shows "Devcon 52345 Plastic Steel Epoxy" - as winner.
Not sure how it will hold as thread.

Overall on Google, "J-B Weld 8272 MarineWeld Marine Epoxy" seems to be the strongest.

This guy tests epoxy and putty to repair aluminium threads, both by totally filling the hole and drill/tap it.

He also shows the good old copper wire trick.
What are your thoughts about that??

First thing that pops Into my mind is "galvanic corrosion!!"

Is it?
In car repairs it's a common much used trick, and stays good for years and years.

I've taken out repaired threads like those after a few years and didn't see any issues.
(Cylinder, carburator on motorcycles) they have a lot (!) Of different heat, expansion, contraction.
And no eaten away aluminium...

So I don't know!

I've seen aluminium motorblocks water cooling insides being eaten away from using copper radiator and not using sacrifice metal.
(Played a lot with Cars from the 60's) that's not a pretty sight.
It really eat away the aluminium.

The coper wire trick...
Nothing.
Not even where the wire is on the outside touching the aluminium.

Your Thoughts please :)

I found forum members who are willing to help me.

I'm going to purchase JB weld, defcon and Loctite
Total about $50,-

Once they arrive, I'll do some testing and let you guys know!

The aluminium on the terminals is a really soft type, as soft as lead.
What makes stripped treads almost more common then non stripped threads after a few mounts..

Best advice for new installation:
Once mounted, never touch again.
Do not untighten to add a wire or lug, better place it on top of your stud and additional nut.
