Product Description

Size: 0.34 Ounce

Permatex Surface Insensitive Threadlocker Blue is a medium/high strength threadlocker for general-purpose applications. Especially well-suited for 6mm to 20mm fasteners that have a slight oil film, this threadlocker prevents loosening due to vibration. Oil resistant and removable with hand tools for easy disassembly. Applied as a liquid or gel, threadlockers are superior to conventional lock washers, nylon inserts, and other mechanical devices because they secure the entire fastener assembly against loosening from shock and vibration by filling the space between threaded metal parts, curing to form a tough, adhesive bond and seal. They also seal the threads against leakage, preventing rust and corrosion.

EDIT (March 2010): It's still holding tight after 1.5 years!
----

Brief summary: It's been working great for over 3 months on my bike.

Longer version:
The left crankarm on my 20+ year old bicycle was coming loose every month or so. The local bike shop said that there was nothing I could do short of tightening it and that the problem would get worse until I replaced the crankarm (a >$100 fix and lots of fun trying to locate an overpriced unused vintage part on auction sites).

I researched the problem online and came across a few mentions of people using Loctite threadlocker to fix the problem. I decided to get the Loctite 243 since it is resistant to grease. Unfortunately, the local shops only carried Loctite 242 (not oil resistant). Amazon carries Loctite 243, but it is through a third party vendor which charges as much as the item costs for shipping. Fortunately, I came across this Permatex threadlocker, which is also grease resistant (#24300) and is offered with free shipping. My impression is that this is the same exact product as the Loctite 243, but rebranded.

Over 3 months ago, I removed my crankarm and wiped the gunk off both the male and female threads. I applied Permatex to the male threads and screwed the crankarm back in. I let it sit undisturbed for 2 days to allow the stuff to fully cure. I have been riding my bike almost everyday since then (about 1000 total miles), but the crankarm has not come loose.

I'm so impressed by this product that I decided to use it on other screws that would periodically come loose (like on my rear rack). Everything has stayed in place.

If you're unfamiliar with these thread locking compounds, be aware that there are several versions of the Permatex and Loctite.

I used Permatex Threadlocker Blue and found it much easier to control, more viscous, than Loctite's product. It is more resistant to 'running' off of whatever substrate you apply it. I've used it on tiny screws to larger bolts. It works flawlessly. The higher viscosity makes it like working with a gel. I will buy more of this product. Also, the bottle makes applying the product much easier when compared with the small tubes. Excellent threadlocker that works and can be undone with a left turn of the screw head or bolt. Permatex Threadlocker Blue is an exceptional product.

Have a loose screw?

A small amount of threadlocker on the threads will act like glue around them holding the screw in place. It lasts too. You can break it open by turning the screw with a screwdriver.

Great stuff!!

I use this all the time. NIce to find the "surface insensitive" type, I didn't know it existed. With this type I don't need to degrease everything - just wipe it off and put a drop of thread-lock on it. Good to go.

Worked on my threaded barrel cover, and slipping forearm (rail) on my SBR once my armorer showed me the correct way to apply. Be sure to read the directions, and apply sparingly, as it can be a bear to remove what you "locked" it with. Loctite can be slightly easier to remove what it was used on, and I got used to it racing cars years ago. But this threadlocker did just fine, and the cover and forearm have not budged in service. No current need to remove them, so can only speak to my initial removal of the cover when I put too much on the threads. One drop to me was larger than the head of a pin, but for the cover, that was all that was needed. The forearm needed more. Experience is the best teacher, but can be frustrating (chuckle).

It does what it's designed to do, holds bolts in place, yet allows removal without a lot of stress. My only regret is that I didn't get a bigger bottle.

The bottle dispenser is a little difficult to use without applying too much or too little. Otherwise the thread lock works just fine.
