Diagram of threadlocker placement
Diagram of threadlocker placement

Threadlocker 262 is applied as a liquid to the threads of screws, nuts and bolts before assembly. The red, high-strength formula keeps connections securely tightened, even during the most severe vibration, shock and stress. Threadlocker also seals out air, water and grime to prevent rust or other corrosion from forming, ensuring that the connected assemblies will remain sound for a long time. Uncorroded assemblies come apart easier and can be reused.


This threadlocker requires heat (500F) to free parts for disassembly with hand tools. Five minutes' application of a torch may be required. Disassemble while parts are still hot.


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, zinc, galvanized steel, magnetite steel, pure aluminum, titanium, magnesium, gold, silver, plastic, cadmium, Iconel, natural or chemical black oxide and anodized aluminum.


Klean 'N Prime can speed the cure rate of Threadlocker 262. This is especially helpful when you are applying the adhesive to any material, active or inactive, in colder temperatures (below 70 F).

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



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



by:

Worked as expected.



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:

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:

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.

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

  • Is there a Way to Lock D-Ring Shackles to Front Of Jeep Wrangler Bumper
    Most Jeep guys leave the D-rings inside the Jeep or torque down the pins so tight that it would take a very determined thief to get them. You can also try a thread locker like the part # LT37420 to make them even harder to remove.

  • Securing Axle U-Bolts With Loctite
    Though it is not completely necessary to use something like Loctite's Threadlocker # LT37420, there wouldn't be any adverse affects either. Most U-Bolt kits do come with lock nuts making them more secure than standard nuts, but you can definitely apply # LT37420 to completely secure their purchase on the U-Bolts.

  • Anti-seize Product Recommendation to Install a Trailer Hitch on a 2007 Honda Fit Sport
    For 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...

  • What Color or Strength Loctite Do I Need to Install Wheel Studs?
    Yes, you will want to use the Loctite Threadlocker 242 - Medium Strength - 1/4" to 3/4" Nuts/Bolts item # LT37418 to install the Redline Replacement wheel studs item # 25-53. This is the blue one you will be able to remove your studs in the future if you need to replace them. The red Loctite Threadlocker 262 - High Strength - Up to 3/4" Nuts/Bolts - 0.20-Fl-Oz Tube item # LT37420 is the one you would either want to use or stay away from if you don't plan on removing the bolt.

  • Roadmaster Falcon All-Terrain Tow Bar Will Not Lock Into Place
    I spoke with my Roadmaster representative, and explained the problem you are experiencing. There is not a repair kit available for the problem you describe, but my rep told me that is sounds as if the anvil bolt on the end of the inner arm has come loose. This is a very simple repair. Remove the inner arm from the outer arm, and locate the anvil bolt on the end of the inner arm. Remove the bolt, and apply some red locktite (part # LT37420) to the threads and reassemble the arm.

Lippert said that when you bolt the footpads to the jacks, you need to torque them to 132 ft-lb. They said to make sure to use Loctite Threadlocker 262 - High Strength - Up to 3/4" Nuts/Bolts - 0.20-Fl-Oz Tube, # LT37420 on the footpad bolts and do not try to remove the bolt once it is tightened as removing the bolt could result in damage to the cylinder.

    I spoke with my contact at Draw-Tite and she stated that Gooseneck Trailer Hitch, # 9464-35, will fit the diesel models of the 2006 Dodge Ram 2500 Mega Cab with a 6 foot bed. You may also need some Loctite Threadlocker, # LT37420, for installation if you do not already have some.

    We don't have an installation video for the Replacement Gear for Lippert Single and Double Electric Coach Step # LC301696 as of yet (March 2019) but I was able to track down some installation tips from Lippert for you. To replace the gear plate you need to first remove the entire Coachstep assembly. You will need to use a hex head wrench or hex head bit in a drill to remove the gear plate bolt. This is installed with some Loctite so you might need to apply some heat for the bolt to move....

  • Is Threadlocker Required To Install A Trailer Hitch Receiver?
    To install the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13119 or any hitch, there is not a requirement in the instructions to use any threadlocker, but I personally think it is wise. The instructions say to periodically check to ensure fasteners are tight, but I don't believe most people actually do that and Loctite Threadlocker 262 - High Strength - Up to 3/4" Nuts/Bolts - 0.20-Fl-Oz Tube # LT37420 would be a good idea.

  • Troubleshooting Wear On Folding Hitch And Recommendations For Hardware
    If your bolts are getting loose, I recommend using Loctite Threadlocker 262 - High Strength - Up to 3/4" Nuts/Bolts - 0.20-Fl-Oz Tube # LT37420 and torquing your bolts to the manufacturer specs. The Loctite will keep the bolts from coming loose and prevent further wear because of loose hardware. If you need to replace the unit you currently have due to the oblong holes, I recommend the Fulton Fold-Away Coupler Hinge Kit for 3" x 3" Tongue - Bolt On - Up to 5,000 lbs # FHDPB330301.

  • Is Thread Locker Recommended Installation Hardware of etrailer Brand e98906 Trailer Hitch
    If the # e98906 hitch installation hardware is torqued according to the instructions, it won't be necessary to use # LT37420 thread locker. You can certainly do so if you wish, however please note that the torque specs mentioned in the installation instructions are for dry torque. If thread locker is used you'd use different torque specs (wet torque) which can be looked up online dependent on the size and class of the fastener.

  • Trailer Spare Tire Carrier Recommendation for Aluminum Side Wall on Utility Trailer
    For your Aluma Utility trailer with aluminum side walls, I recommend the Fulton Hi-Mount Spare Tire Carrier # FSTC1000301. This spare tire carrier is zinc plated so it won't have galvanic corrosion issues with your aluminum side wall and it has two plates to hold the back side of the carrier and disperse that pressure. Aluminum is a softer metal, so you will want to be careful when tightening to make it snug and yet not over-tighten and deform the side wall. If you want to make sure...

  • Installing A Replacement Foot Pad For Lippert Hydraulic Ground Control Level System
    The replacement Foot Pad for Lippert Hydraulic Ground Control Leveling System - Qty 1 # LC324269 needs to be torqued to 132 ft-lb and Lippert recommends using some Loctite Threadlocker 262 - High Strength - Up to 3/4" Nuts/Bolts - 0.20-Fl-Oz Tube Item # LT37420 to prevent the bolt from loosening. You are correct with the placement of the washer and o-rings.

  • Should Loctite Be Used to Install a Curt Hitch on a 2014 Honda Odyssey
    There's no reason you couldn't use Loctite like part # LT37420 when installing the Curt hitch part # C13068 but as long as you torque the install hardware down to the proper torque figures in the instructions you wouldn't have any problems with the bolts loosening. I attached an install video for this hitch for you to check out as well.

    I understand your concern. I called Lippert to verify that the 132 Ft-lb of torque and use of Locktite is still valid. They said that was the requirement and there were no alternative instructions. The assumption is that this is the method they used for installation and that by removing the foot pad you will run the risk of damaging the cylinder. If you need to remove it in the future the only way to release it after red Loctite is used would be by applying heat. I also verifed the order...

But you may need to tighten your adjustable anchor points as shown in the demonstration video that I attached (about the 5 minute mark).
