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).

Very good product.



by:

good stuff, been using it for years



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:

Loctite always works..



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:

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

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.

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

  • Recommended Parts Needed to Flat Tow a 2018 Jeep Wrangler JL or JL Unlimited
    For your 2018 Jeep Wrangler JL, I recommend starting with the Roadmaster EZ5 Base Plate Kit # RM-521453-5. This kit has removable arms to give you a very clean look when not flat towing your Jeep, and also gives you a clean connection to your tow bar when towing behind your motorhome. I recommend installing this base plate using Loctite threadlocker # LT37420 to keep your hardware from vibrating loose over time. For your tow bar, I recommend the Roadmaster Nighthawk All Terrain, Non-Binding...

  • 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.

I recommend using Loctite Threadlocker # LT37420 for this installation. For your vehicle wiring, I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56304 which is the easiest kit to install with no splicing required and connects directly to the Honda wiring harness behind the tail lights. You will also need the 48" Long 4-Pole Loop...

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.

    The Roadmaster MS Base Plate Kit - Fixed Arms # 2503-1 does not have the removable connections like the # 2506-1 or even the # 2506-3. The removable option gives you a cleaner look when not connected, but the connection will be similar.

  • Do I Need To Use Thread Lock On The Bolts When Installing A Hitch?
    Hey Peter, Although thread lock is not necessary to install the hitch, # e98838, it is always recommended. Its especially recommended on applications where the bolts are exposed to repeated vibrations/road impacts like a trailer hitch. All it is going to do is really secure those bolts in and keep them from coming loose after frequent towing. I recommend # LT37420, Loctite, we use it on all of our hitch installations at our facility. Are you looking to tow with your hitch or use something...

For a base plate kit that is compatible with your vehicle, I recommend using the Blue Ox Base Plate Kit part # BX1721 as this is the only base plate kit we have list as a fit with the Z71 and Trail Boss packages.

  • What are the Toques Specs for Installing My Titan 60 Surge Brake Actuator onto My Trailer?
    Hello Robert, The torque specs for your Titan Model 60 actuator aren’t listed in a specific manual, but the mounting bolts that attach the unit to the trailer frame typically follow standard torque values based on their size and grade. For example, if you're using Grade 5 bolts, a 1/2" bolt should be torqued to around 75 ft-lbs, and a 5/8" bolt to about 150 ft-lbs. These are pretty common across trailer setups. As for the other two bolts that are part of the sliding mechanism inside the...

    For 2010-2013 and 2014-2015 Chevy Equinox models, there are a few components you will need to safely flat tow your vehicle. You will need base plates, a tow bar, safety cables, tow bar wiring, a supplemental braking system, a high low adapter, and a few other parts for power and fuses to make sure everything works together properly.

  • Replacement Crossbar Hardware for Yakima Y01151 OverHaul HD Truck Bed Ladder Rack
    Although Yakima doesn't offer the M8 x 18mm security Hex Screw as a separate item, they do offer the screws as part of their # Y42XR replacement hardware kit which includes 4 of the M8 x 18 screws, 4 flat washers, 4 lock washers and 2 nut plates. As you can see by using the provided link, the kit is very inexpensive and it never hurts to have some spare parts around. I'd also think about using some thread locker like # LT37420 to make sure the hardware doesn't back out again.

    The Dexter Single Axle Heavy Duty Suspension Kit # K71-403-00 technically will not have a torque specification. However, I have been asked this before and was informed by Dexter that what you need to do is tighten them down to the point of either pinching the leaf spring or all the way to the shoulder of the bolts. If you start pinching the head of the leaf spring before hitting the shoulder, you will need to back the nut off a little to let the spring move, but not so loose that it can...

  • 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...

    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...

I recommend moving the rack up and down slightly as you tighten that threaded bolt. That should secure the shank to your hitch.
