does JB Weld “really” fix aluminum threads

I’ve heard a lot of people talk about fixing aluminum threads with JB Weld. I’ve got the perfect application, so will put it to the test. This application has no heat on it, it has a torque spec of about 18 foot pounds.

You should completely fill the hole, let it cure and then re-tap it. Putting an oily bolt in there will only serve to prevent the JB Weld from curing properly.

You'd get a lock nut behind that mount.

Excellent video and guidance. Many thanks to you. 🌺🌺🌺

im curious as to how malleable jb weld is well after its curing period; the product is marketed as being very resistant and holding high amounts of tension but wouldnt it be counter productive to 'cut' into it with a bolt's threads? kind of like carving wood.

nice vid, thx!

The ATF fluid messed up the strength of the jb weld. No mold release needed if once it cures you back out the bolt. I have used this on valve covers 6.5ft lbs and head bolts 20ft lbs.

Since the threads are partially damaged/stripped, how about re-creating the threads to the next larger size and using a larger bolt as a permanent solution?

congratulations nice work, but where did you put the screw in a jar of oil? if so and not to stick to the glue jb weld ?

[lElektrongeek]

You should try some helical inserts they work very well !

Exactly what I was looking for. Thanks.

What about adding some steel wool shavings to the JB Weld?

These electronic footmeter is awesome. Where can I buy it and can I use it for newton meter?

[memybikeni]

I’ve tried completely filling the whole and drilling/taping, didn’t work, just crumbled up, it’s not good for this type of application.

You should try out the HI heat JB weld stick putty

[bobgreene]

Where did you buy your brush for the bolt hole? I can find no brush that small.

[bitchybecca]

How about filling the hole up and then retyping it to that size

[homerbob]

The only good succesful use of jb weld i had was to fix a a small hole in fuel tank. Wenever the part is subject to a stress you can be sure jb weld will fail

JB Weld specifically says DO NOT USE ALCOHOL. Your issue is residue.

[davidschmidt]

This is what happens when people get even a bit careless with impact drivers.

[andyg]

Yes jb weld it will hold the bolt in place maybe.. lol.. but in /out all time, sceptical...

It's not possible coz' epoxy is still plastic but aggragates that are hard should be added to the epoxy (shredded carbon fiber will strengthen it to aluminum strength). 50/50 ratio.

God bless.
