This diagram illustrates the use of this threadlocker:


diagram of threadlocker in use

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).

great! I have a set of these and ran out of the blue. Couldn't find it locally except in the size that holds only half as much. I was happy to find it here on etrailer. Great job etrailer.



by:

Just what I was looking for at a great price.

These were suggested as I was replacing my suspention system. They work well. Only thing I woould say is that they are a little longer than I think they should be. Made it hard to use my torque wrench.



by:

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!

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.

Locktite makes very good products, and this is another one. Used for fasteners that are already assembled/torqued and it wicks into place. E-Trailer completed the order process and delivered the product as expected, so well-done to them.



by:

The instructions and accompanying videos on your site made this a DIY installation that came out perfectly.



by:

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.



by:

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.



by:

This stuff works! Used it to install my trailer hitch bolts.



by:

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.



by:

Easy to use, and works perfectly for locking in threaded wheel studs.



by:

Good price, fast shipping, fair postage....... What else could you ask for?



by:

For the installation the instructions were good, but watching some videos made it much easier to take apart a brand new car. All went well. Installed on a 2020 Chevy Equinox 2.0



by:

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.



by:

Worked as expected.



by:

Loctite 243 (blue) worked great on my Harley Road King Custom primary asse3mbly. Great service and fast shipping. Would recommend etrailer to anyone. Will buy from in the future.

They have great prices and fast shipping, What else could you ask for!



by:

Needed Loctite 262 to assemble my Harley Road King primary. Great service and fast shipping. Will buy from etrailer in the future.



by:

Product worked as advertised. Can't ask for more than that. etrailer.com was very good at expediting my order. Thanks



by:

Loctite used on base plate installation. Worked well as always.



by:

Reinstalling clutch, equipment manufacturer specifies using LOCTITE 262 on clutch reinstall. Unable to locate 262 except in large quantities in my area. Etrailer had the small quantity 262 and responded to my order immediately. Completed clutch reinstall and equipment is running fine. Thanks Etrailer



by:

Product was exactly as advertised, and as I wanted. Delivered as stated. etrailer is a great company to work with. This is the second vehicle I have outfitted, and they have had great videos and directions with their products.



by:

Used it for the towing equipment on our Jeep and it has done it's job by keeping all the bolts in the same position. Would highly recommend

  • Is Red Loctite Required to Use Roadmaster Hitch Mounted Spare Tire Carrier RM-195225
    It is not necessary to use red Loctite like # LT37420 on the hitch bolt of the Roadmaster Hitch Mounted Spare Tire Carrier # RM-195225. It is optional, like you mentioned, and the intent with the Loctite is simply added tightness at the connection and security since the bolt is anti-rattle and not locking. What you can do instead is use Loctite Blue # LT37614 like you mentioned, and instead of the hairpin on the hitch bolt, use the RoadMaster Quick-Disconnect Padlock # RM-301.

  • Should Thread Locker be Used when Installing Trailer Suspension U-bolts
    Lock nuts alone should have been fine but you could use some Loctite, # LT37614, for extra protection. Make sure to use the blue Loctite and not the red version. The red would make it very, very difficult to remove the nuts. Since you mentioned the lock nuts failed then I recommend replacing not just the nuts but the u-bolts as well. The threads could have been damaged on the u-bolts so it is better to go ahead and replace them. I have included a link to our trailer suspension u-bolt main...

  • Does Curt Trailer Hitch 12038 Come with Lock Washers for Installation on a 2003 Subaru Forester
    Curt Trailer hitch # C12038 does not include lock washers. So it wasn't that you didn't get them it is that the hitch doesn't come with them. Using Loctite would be a great idea. Blue Loctite is should be all you need, # LT37614. Because the red Loctite is pretty much permanent. So should the hitch need to be removed for any reason, it would take pneumatic tools if you used red Loctite. Also, make sure the bolts are torqued to the specifications in the instructions. If they are too loose...

  • What Hardware Is Needed To Mount The ARB 813402 Awning To A 2019 Honda Odyssey?
    I did a little research on your ARB 813402 awning, and I was able to find out that you can use the Replacement M6x35 Square Head Bolt for Thule OutRide, ProRide, ProRide XT, UpRide Bike Racks # TH33RV with the washer # 951-1016-54. I wasn't able to find a definitive length of bolt you'd need, however if # TH33RV is too long you can just cut the bolt down to meet your needs. Finally, I also recommend using some blue medium strength Loctite like the # LT37614 to keep everything secure.

  • Concern About Nuts Vibrating Loose on Brophy Recessed Trailer D-Ring Tie Down # RR5K
    You will want to use the included hardware to install the Brophy Recessed Trailer D-Ring Tie Down, part # RR5K. If you are concerned with the lower bolts vibrating loose over time, I would recommend using Loctite Blue Stick Threadlocker, part # LT37614. I have linked instructions for the Threadlocker for reference.

  • What Can be Done to Help Rock Tamers Bolts Keep From Loosening
    What you can do to keep the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2" Hitches # ERT00108 from loosening up - along with torquing to spec - is apply some Loctite Blue Stick Threadlocker # LT37614. The Loctite Blue # LT37614 will help secure the bolts and keep them from loosening, but won't permanently affix them so the bolts will still be removable if need be. Just keep in mind it takes a full 24 hours for the Loctite to fully set.
