This diagram illustrates the use of this threadlocker:
Threadlocker is applied as a paste to the threads of screws, nuts and bolts before assembly to keep them securely tightened, even when vibration occurs. Threadlocker also seals out air, water and grime to prevent rust or other corrosion from forming. Nuts and bolts that aren't corroded last longer and can be taken apart more easily. Standard hand tools can break the seal of the threadlocker, allowing you to remove treated nuts and bolts, which then can be reused.
This threadlocker is anaerobic (hardens in the absence of air) and requires contact with an active metal to cure. Active metals (those that tarnish, corrode or rust) include brass, copper, bronze, iron, soft steel and nickel. If both parts to be joined are made of inactive materials, Loctite Klean 'N Prime primer must be applied to one of the surfaces for curing to occur. Inactive materials include plated parts, stainless steel, galvanized steel, magnetite steel, pure aluminum, titanium, magnesium, gold, silver, plastic, cadmium, Iconel, zinc, natural or chemical black oxide and anodized aluminum.
Klean 'N Prime can speed the cure rate of Threadlocker Blue Stick. This is especially helpful when you are applying the adhesive to any material, active or inactive, in colder temperatures (below 70 F).

I will never go back to liquid threadlockers. This should be the industry standard. No mess, no waste, much more control, no spilling, and countless more benefits. I use it for small screws, so it makes it much easier to apply a more reasonable amount so I don't end up stripping the torx heads when I remove them from having to put too much torque on it to remove them. My only complaint about this product is that I didn't find it sooner!
Comments
As I said in my previous review, I use this product on small screws, so I only use a little at a time. For that reason, I dont go through it very quickly, and after a year or seems to have maintained the vast majority, if not the entirety, of its effectiveness.

Review from a similar Threadlocker in Lubricants Sealants Adhesives
This is a really solid base plate. Installation for the Pontiac Vibe was is definitely more involved that installing the alternative (Road Master). The Road Master base plate just bolts through existing bumper holes and an engine mount. This base plate is bolted directly to the frame just behind the bumper, with four 3/8" grade 5 bolts in holes you have to drill after clamping the base plate in place. I found it easy to get the required height (3/4" below bumper) but simply using a 1x3 piece of lumber. You also have drill a 1.25"hole in the frame to gain access to the inside of the frame. Tricky part of this install is getting the nuts, which are welded to a 1" plate and a ~14" steel rods, into place to be line up with the holes. It is a little hard to see. I also recommend making sure the bolts actually thread easily on to the nuts before putting the nuts in the the frame. I had the misfortune of one of the either cross threading or jamming, and I ended up having to cut the bolt head off with a sawsall using a metal blade. The bolt had not gone very far into the nut before it jammed so I was just able to get the sawsall blade behind the head, and cut it off, holding the head with a pair of vice grips. If that hadn't worked I would have had to take the car to a shop with oxy-acetaline torch to have it cut off. I was able to fish the cut of bolt out for the frame with a bent coat hanger. The first photo is of the base plate after I cut off the bolt.
Blue Ox support was GREAT! I sent them and email explaining that I needed new nuts and bolts, and they sent the needed parts (at no charge!). I just had to put my install on hold for several days.
The second problem I had was in attaching the electrical harness recepticle to the tubes on the to bar. One of the self tapping screws twisted off as I was tighting it. I ended up cutting of 1/2" of the tubes (with the sawsall) and then tapping the tubes with 1/4x20 threads, and regaining the length cut off with the bolt. My recommendation to blue ox, is that they tap these tubes with to 1/4x20, and provide regular bolts to attach the recepticle. The second picture showes the result.
When I showed the 3rd and 4th pictures to my mechanic, he was impressed and said, "That looks really solid!" The last picture shows the front of the car after I have started to assemble it (with the styrofoam padding on the bumper, and the draw bars in place.
The solidity of the Blue Ox engineering and the FABULOUS customer support has totally turned my into a Blue Ox fan. I'm glad my RV dealer suggested that I go with Blue Ox instead of the slightly cheaper solution, that would have been much less solid.

I ordered multiple Roadmaster products from etrailer.com to rebuild a used Roadmaster Sterling towbar and prepare my car for its first time towing behind the motorhome. The etrailer people are great to work with, the prices are good, delivery is quick, and free shipping for all of my orders. The technical support at both etrailer and Roadmaster is the best.

Review from a similar Threadlocker in Lubricants Sealants Adhesives
Bought this product after watching the video how to install base plates on 2014 Honda CR-V. If you read the instructions talks about checking the bolts periodically for torque, now I don't know how many people are going to spend 4 hours pulling off the front bumper to this. So for peace of mind use this product so bolts won't come loose.

Review from a similar Threadlocker in Lubricants Sealants Adhesives
I have used the LocTite products for many years. They make several grades of thread locking fluids, each appropriate for specific uses. Their products do exactly what they say they will; and will secure threaded parts from vibration or lock them together permanently. Your toughest choice will be in determining which product is most appropriate for your use. My recommendation is to start with the lowest strength and work you way up as needed. Just remember that without special tools, permanent means permanent with this product. The lower grades are very strong in preventing vibratory loosening.

Locks the threads so the screw doesn't back off. Its holding down a tongue pivot bolt and a anti-rattle bolt currently. Only time will tell if it stays put per long run. Put it was exactly as desired.

- Thread Hitch Bolt Coming Loose on Kuat Transfer Bike RackAre you using both the flat washer and the lock washer with the hitch bolt on the Kuat Transfer TS03G? The lock washer would prevent the bolt from backing out. That is unless the threads on either the bolt or the nut in the rack shank are damaged. Also, make sure you are inserting the bolt from the right (passenger's) side. If you put it in the other way there won't be enough threads to thread into the nut. I have not heard of this problem on the Kuat Transfer. You could use BLUE Loctite...
view full answer... - How Does Gustafson RV Ceiling Light Mount to the CeilingI went out to the warehouse to inspect Gustafson RV Ceiling Light. There is a mounting plate beneath the dress cover. The fixture is held to the plate/ceiling with 2 screws. You might also be interested in some blue Loctite, # LT37643, to prevent hardware from backing out on this or anything mounted with screws or bolts.
view full answer... - Is Loctite Required When Installing a Trailer HitchIn most cases Loctite is not required when installing a trailer hitch, but it would not be a bad idea. I suggest using the Loctite Blue Stick Threadlocker, # LT37643, which will provide a secure grip and protect against water and grime.
view full answer... - Do Axle U-Bolt Nuts Require WeldingSpot welding the axle nuts on a trailer would be overkill. Most u-bolt nuts are just fine with the nyloc nuts that are used on them, or you could use Loc Tite like part # LT37643.

I do have some suggestions for you that might help you get a tighter fit for your hitch bike rack. If you are still getting 1 - 2" of movement between your hitch bike rack and your hitch receiver, you can tighten that hitch bolt while you are moving the Kuat Transfer in the hitch receiver. If you tighten that bolt as you are wiggling the rack, you should start seeing less...
view full answer... - Is Loctite Suggested When Installing Trailer Hitch ReceiverWhen installing a trailer hitch receiver like # 75081 we do not suggest using Loctite on the bolts and nuts because the manufacturer doesn't. It isn't a bad idea in most cases to use # LT37643 because it will keep the hardware tight. The only situation where I wouldn't recommend it is when you have weld nuts in the frame, which isn't an issue with this hitch.
view full answer... - Recommended Torque Specs for 9/16 and 1/2 Inch Trailer Suspension HardwareIf you will be using 9/16 inch fasteners then torque them down to 110-114 foot pounds. If using 1/2 inch torque them to 76-78 foot pounds. You can find all sorts of different torque specs for the same size bolts or nuts and they will all be around these same figures. If you use Loctite use the blue kind, such as # LT37643, which will allow you to remove parts using hand tools. The red kind is going to be too strong. Also make sure the Loctite only goes on the threads and on any part that...
view full answer... - Solution for Reese SC Sway Control Pads that Fell OffIt is not common for the pads of the Reese Sway Control to fall off. We haven't had any customers report back to us and say they lost their pads. The best recommendation I can make would be to make sure you get the screws good and tight and use some thread locker like Loctite Blue part # LT37643.
view full answer... - Can Trailer Hitch Hardware be Greased to Resist Corrosion for a 2012 Mazda 3 HatchbackThe Draw-Tite trailer hitch, # 24843, uses lock washers and conical tooth washers that prevent the nuts from backing out. I would say that the use of grease is not prohibited by the instructions (see link) but that there are some other options. You can use blue Loctite, # LT37643. The blue version will allow the hardware to be removed (if ever needed) but will also protect the hardware from corrosion. The problem with grease is that it can cause other particles of dirt and things to...
view full answer... - Anti-seize Product Recommendation to Install a Trailer Hitch on a 2007 Honda Fit SportFor Draw-Tite trailer hitch # 24776 for your 2007 Honda Fit Sport there isn't a specific recommendation for anti-seize products for the installation hardware. Loctite # LT37616 would work fine. But if you are talking about thread locker then there is just one thing to consider: how difficult do you want it to be to remove the hardware? If you use blue Loctite # LT37643 then the hardware can still be removed using hand tools. But if you use red Loctite # LT37420 then power tools would have...
view full answer... - Should Loctite be Used to Put Together Curt 4 Bike Platform Rack # C18087If it were me I probably would not use Loctite when assembling Curt 4 Bike Platform Rack # C18087 simply because it isn't needed. However if you want to err on the side of caution and chose to use Loctite I recommend using blue Loctite # LT37643. The blue Loctite is the less severe duty formula meaning you will still be able to take the rack apart with regular hand tools. Other formulas are much stronger and would require power or even pneumatic tools in some cases.
view full answer... - Is 8 to 9 Full Turns Enough for Trailer Wheel Lug NutsThis is a tough one. I did a little math and if you have 1/2 inch studs on the hub then every full rotation of a lug nut is approximately 1-1/2 inches of rotational travel and on standard 1/2"-20 threads the distance from one thread to the next is approximately 0.05 inches. That would mean for 8 to 9 turns the lug nut would be gripping 0.4 inches to 0.45 inches of the wheel stud. That isn't very much but it could be enough if you were to use blue Loctite # LT37643 to prevent the lug nuts...
view full answer... - Red or Blue Loctite for Installing Trailer HitchUsing Loctite when installing a trailer hitch is not required but it can certainly be used to create an even stronger bond. Blue Loctite like the Blue Stick # LT37643 is plenty sufficient for this application. As long as the hardware for your hitch is properly torqued down according to the installation instructions though Loctite is not needed for a safe and proper connection to the vehicle.

The most common use is on the side of the trailer welded to the trailer frame. You see this type of application often on the sides of flat bed semi-trailers. Welding by a qualified weldor is the approved method for attaching the Truck and Trailer Winch. If you wanted to bolt the winch to the frame you would have to drill holes in the base and use bolts washers and lock...
view full answer... - Lugs on Dexstar Steel Mini Mod Trailer Wheel Coming LooseI have a couple of things that you can do to troubleshoot the lugs coming loose on your Dexstar Steel Mini Mod Trailer Wheel # AM20789. You can start off by making sure that all of the studs on your hub are not loose. Sometimes over time they might start to loosen up, You will also want to make sure that you have the correct cone angle on your lugs. For the Dexstar wheel you will need to make sure that you are using a 60 degree cone. If you are using lugs with a 90 degree cone or that...
view full answer... - Rivet Nuts Coming Loose on Reese Strait-Line Weight Distribution SystemDrilling out the rivet nuts # RP58507 could actually cause the holes they are in to enlarge which would allow them to come out of their respective holes easier. If that does happen then the only solution would be to use a bolt and nut and run the bolt all the way through the trailer frame. Another option is to use some blue Loctite # LT37643 which will prevent the bolts from backing out and still allow you to remove the bolts using hand tools should the need arise.

You might be able to get to it without taking the whole # F2430 kit apart but you have to be careful to not let the axle hang from freely in the process because that would damage the air bags. You would need to remove the air fitting and the nylon jam nut that holds the bag to the upper bracket. Then you would need to compress the air bag enough to be able to get a tool up there to loosen that flat head Allen...
view full answer... - Replacement Screw-In Wheel Stud for Boat TrailerThe part you referenced, Redline # 25-53 Replacement Screw-In Wheel Stud, has a fine thread pitch and a 1/2-inch diameter. If this matches your trailer's wheel stud then you can use a lubricant to remove the old stud and replace it with this one using a thread lock like Loctite Blue # LT37643.
view full answer... - Using Anti-Seize Compound on Trailer Hitch Mounting BoltsUsing anti-seize compound on the hitch mounting bolts is not necessary. Because of the lubricant properties, you'd need to lower the torque specs in order to not over tighten the bolts. You would be better off installing the bolts dry and tightening them to the torque rating mentioned in the hitch installation instructions. Using something like a Loctite Blue Threadlocker, part # LT37643 would be a better idea. The waxy texture makes threading bolts in place easier, but gets tacky as it...

To prevent that this mirror has lock washers but you can also use some blue Loctite # LT37643 to further prevent the hardware from loosening. As far as customer reviews one customer said they vibrate a lot and another said they don't vibrate much....

If tightening the hardware still does not fix the teeter tottering issue that you are experiencing, it is possible that the wheel hoop arms or the center mounting bracket could have been bent or damaged during use.
