Thread lock - looking for a decent one
Has anyone found a thread locker that contains a decent amount of product and isn't ridiculously expensive?
I bought one of these and there's hardly any product in the bottle (supposedly 10ml) - I've used it on 4 bolts and there's hardly any left! |

Check out this list: Thread lock
We used to use Caterpillar brand thread lock on heavy plant equipment (Caterpillar buldozers/scrapers etc), Loctite do the equivalent approved by Cat. You wont buy better. Just take the part number you want and search for it online. |

Then you're being too liberal with it. A single drop from the nozzle is sufficient to do the job on bolts up to 5mm diameter. The problem is, thread lock fluids are rather thin liquids and difficult to dispense efficiently. And because of the way they cure (anaerobically), they're more expensive than most other servicing fluids. TC |

Beat me to it, I was gonna ask what mammoth bit of machinery the bolts had come from. Like T-Cut says you only need a drop on smaller bolts and maybe two on large bolts >m10. You don't need to cover the whole thread either. Some prefer to use the wax type thread locks like this one https://www.amazon.co.uk/Loctite-248...omotive&sr=1-1

I think I have something similar to https://www.ebay.co.uk/p/Loctite-248...yABEgIvOPD_BwE
this may well work https://www.carbuilder.com/uk/black-...iABEgJH_fD_BwE got some on the lid to tin seal, could not remove the lid. I'm joking, don't use por 15 you wont get the nut and bolt apart and I mean you wont get the nut and bolt apart maafee2 |

Threadlocking systems come in various grades or strengths. Check the manufacturer's data sheet. If you need to stabilize a bolt that may well need removal later (eg: a cambelt tensioner bolt) get one that can be easily undone again. There are three or four hardness bands. The hardest makes a thread that's impossible to slacken and you'll shear the bolt before the threadlock breaks. Having to heat a belt tensioner bolt to 250C to degrade the threadlock is not the way to go.

Always read the manufacturers instructions as to whether you put a drop or fill a joint. It does vary.
We always recommended loctite products as it was reckoned that they were more but not totally tolerant of contamination on threads. |
