Is this threadlock and should I apply more?
jps - 23/9/18 at 04:38 PM

The hub carrier bolts from my Sierra donor have blue stuff on the threads. I assume it's a threadlock. Looks like brand new Ford bolts for the same purpose have the same on them - e.g. https://www.fordpartsuk.com/rear-hub-mounting-bolt

The Haynes manual makes no mention of reapplying a threadlock when replacing the bolts on reassembly, but I thought threadlock needed reapplying once undone?

Should I buy some to reapply and if so, what stuff?

If your reusing the bolts clean them and reapply tread lock

Yes it is, its the same stuff you get when you buy new Flywheel bolts or propshaft bolts. Just clean off the old and apply new.

Halfords do small bottles of Blue threadlock which should be fine for your needs.

And do not that it has a use by date on the bottle so don't be retiring it for important stuff many years down the line.

I did not understand that...
Do you mean it goes bad?
Or the other way around?
I have a small bottle from the start of my build.
Not used on anything critical, but I donīt remember either it has a Exp date on it.

I think the point he's trying to make is that thread lock has a use by date.

A quick web search shows Loctite 24 months un-opened and 12 months once opened.

Fasteners where you use thread lock are very often safety critical so to bserve the use by date!

That's news to me. I've still got some in the toolbox from the late 80's! [don't worry, I haven't used it]

When I Googled it I found a *lot* of traces of people asking 'does threadlock have a shelf life' and then them getting a lot of responses like this!

Well, that's my 'learn something new every day' thing for today... my threadlock is about 3 cars old, which is close to a decade in old money.

If this is true, and my Loctite bottle does not have any dates on it,

My car should of fallen apart back in 1991/2

Hi all,

I am sorry my predictive text ruins what should be clear information. I normally check LCB in bed before sleep, often it send me to sleep!!!

Yes Locktite does have a shelf life, once it is applied it is fine though.

I use this on critical components for medical equipment and we have to prove that it is within date when applied. This is how I know.

The deterioration in performance is unknown to me but I certainly notice a difference in between the stuff I handle at work and the 10 year old stuff in my garage!!

Ok.
Thatīs what I thought.
Iīll consider all of the above comments next time I buy/use.
And if you consider "Use Before Date" it may not be that expensive to buy small tubes instead of the larger bottles -cheaper per ml, as they usually last a very long time... At the end of which, you just toss the remaining and buy another.
