JevvuThread Lock Blue and Red, Thread Locker Medium and High Strength, 50mlx2 Lock Tight Threadlock for Nuts, Bolts, Fasteners and Metals, Against Losening and Leakage

This is a good, large amount of thread lockers for a DIYer like myself. At 50ml each, they are likely to last for a long time.I have tested both bottles (blue is removable, red is permanent) and so far have had no issues at all. It is important to shake them well before use. It takes 20 minutes to hold and gets fully cured in 24 hours, providing a reliable adhesion.The price of £9.99, at the time of this review, is good value for money given the large amount and overall quality of the product.All in all I can recommend these thread lockers.

I used the blue threadlocker on the hinges of our garden gate — they kept rattling themselves loose in the wind, which was driving me mad. Cleaned the threads, dabbed a bit on, tightened it all up, and haven’t had to touch it since. It’s held firm but not too aggressive — I know I’ll be able to get them off again if I ever need to.The red version’s for jobs you’re not expecting to undo again. I’ve used it on a few metal fixings around the shed — things I wanted properly solid. It sets like concrete once it’s cured, so if you do change your mind, you’ll need to heat it up with a blowtorch or similar to get it moving again.Both go on easily, no fuss. You give the bottle a good shake, make sure everything’s clean, then just run a bit onto the threads before tightening. It starts to grab after about ten minutes, but I left mine overnight for a proper cure.The bottles are only half full, which looks a bit odd at first, but that’s deliberate — the glue hardens in the absence of air, so full bottles would end up solid.Very happy with the performance so far. The blue’s great for anything that might need adjusting later, and the red’s ideal for jobs you want to forget about. Solid all-rounders, and they’ve earned a spot in my toolbox.

My rear MTB mudguard keeps coming loose and its really annoying, and potentially dangerous so I needed a fix, this seemed to fit the bill perfectly.It's very simple to use, just put a small amount of the blue (temporary) or red (permanent) thread lock onto the thread (where the nut will travel over), tighten the nut and let it set. You don't really need to know how it works, it just does!! I've now ridden my bike for over a month and so far, its done a great job of stopping the loosening, its a been a great choice!Priced at £14.99 (after a 6% discount) and a further 20% voucher at the time of ordering, this pack represents decent value given the fact that you get 50ml of each. I've not used the red yet as I have nothing to trial it on yet, but if its as good as the blue, it will do a great job, just don't get them mixed up! :)

The Jevvu thread locker is a type of glue, but specifically for stopping nuts and bolts from shaking loose. The red one's the strong stuff, proper permanent, good for bits and bobs you don't reckon on taking apart again anytime soon. It says it works on things up to an inch in size and can handle some pretty extreme temperatures, like -65 to 300 degrees Fahrenheit. Mind you, if you do need to get it undone, you'll need to heat it up a fair bit, around 232 degrees Celsius for a good five to ten minutes, before you can get the spanners on it. The blue one's a bit more forgiving, a medium strength, and it's for things between a quarter of an inch and three-quarters of an inch. Same temperature range as the red, but the best bit is you can undo it with your normal tools. You just give the bottle a good shake, make sure the bits you're sticking together are clean, and then just apply it to the threads before you tighten things up. It starts to set in about ten minutes, but you should leave it a full day to properly cure. I used the blue stuff on the hinges of our garden gate, they kept rattling loose with the wind, proper annoying it was. Haven't had to tighten them once since then, so I'd say it's been pretty effective for me.It comes in two strengths, red for high strength and permanent locking, and blue for medium strength and removable locking. It's suitable for metal threads, prevents loosening from vibration, stops rust and corrosion, helps prevent leaks, can handle a wide range of temperatures, and the blue stuff can be undone with regular hand tools. They also reckon it's waterproof and has long-lasting effects.⭐ Not recommended⭐⭐ Consider other options before this one⭐⭐⭐ A decent product that's worth considering⭐⭐⭐⭐ A great product, keep high on your list⭐⭐⭐⭐⭐ An outstanding product, and one of my top choices

This review is for "Thread Lock Blue and Red, Thread Locker Medium and High Strength, 50mlx2 Lock Tight Threadlock for Nuts, Bolts, Fasteners and Metals, Against Losening and Leakage."Good sized 50ml bottles of both temporary and permanent thread locker - the permanent (red) one needs lots of heat to disassemble, whilst the temporary (blue) can be disassembled with strong hand tools.This is designed to bond the threads where the nut and bolt threads are in conteact with each other, and fills the tiny voides between the threads - so to use it, I needed to apply some to a clean bolt in a position close to where the nut will end up...as the nut was screwed onto the bolt, it spread the thread locker in between the threads, and then cured when it had no air contact. I can vouch for the fact that the permanent one was not removable at all after curing !The price at the time of review was around £16 for two 50ml bottles. Not the best price out there, but it does do the job.
