Threadlockers are an ideal solution to secure bolted joints. Bolted joints are common in a variety of products, machines, and vehicles. The fastening of this type of joint is prone to failure for several reasons. When stressed, vibrational, impactive, loaded or thermally expanded.
Bolted joints consist of two essential elements, bolt, nuts, stud, or threaded hole. These two elements are connected via the carving they undergo. An infinity of assemblies can be fastened with bolted or removable joints. They can both be found in the industrial as well as automotive sectors.
Loctite 262 vs. 271: Which are the most useful? The following are two types of threadlocker that are popular. For this reason, using a thread locker is essential to prevent this serious problem. Below, let’s discuss an in-depth comparison of both.

What Is Threadlocker?
Let’s start by learning what threadlocker is and how it works. It is an excellent piece of apparatus that is used mainly to seal any space between nuts, bolts, or fitting threads. Basically, it is a thin, single-component adhesive or glue.
An example of a thread locker’s work is to secure two threaded hardware to prevent loosening, leakage, or even corrosion. There are permanent and removable adhesives available on the market- so, depending on your needs, you can select different products. Check out our comparison in the following section.

Loctite 262 Vs. 271: In-Depth Comparison
Despite being in the same series, Loctite 262 and 271 have vastly different materials. Although similar, they offer distinctly different features and capabilities. Different applications, maximum heats, fastener sizes, and fixture times distinguish them from one another. It’s time to get to the point and see how they differ!
The size of the fastener is the most crucial factor in our comparison. Bolts and screws require threadlockers.
Loctite 271 can be used with screws with a diameter of 3/8″ to 1″. The Mil-Spec Loctite 262 permanent threadlocker tightly binds fasteners up to 3/4″ (20 mm). In extreme chemical and environmental conditions, both are excellent for prohibiting corrosion and rust.
Threadlocker has an inverse relationship between the viscosity and strength of the screw. Generally, when the screw is larger, the parts can adhere to each other better.
Thread locking adhesive Loctite 271 has a low viscosity, methacrylate-based formula with high resistance. Anyway, steel fixtures require 10 minutes, brass 5 minutes, and stainless steel 15 minutes as well.
This Loctite 262 adhesive fluoresces under UV light, allowing it to be monitored. This adhesive is MIL-S-46163A certified. Threadlocker Loctite 262 cures after 24 hours and has only a 10-minute fixation time.
Maximum Heat Stability
With a vapor pressure of fewer than 5 millimeters, the Loctite 262 Series thread locker adhesive achieves superior performance. The Hg content is 27 degrees C, the boiling point is 300.2 degrees F, and the specific gravity is 1.05 at 25 degrees C. For safe use, it must have a flash point more than 199.94 degrees F TCC.
Loctite 271 offers a wide range of temperature resistance, ranging from -65°F to 300°F, and some go as high as 650°F. In hot environments, it loses its effectiveness because of the lack of effectiveness at high temperatures.
Threadlocker 262 from Loctite features an anaerobic cure, medium to high strength, and is also a liquid. It is used to permanently lock and seal threaded fasteners. Despite vibration, heavy shock, and chemical exposure, this threadlocker will hold strong.
This Loctite Threadlocker Red 271 is used to permanently seal threaded fasteners and lock them into place. In the absence of air, the product cures between metal surfaces that are close-fitting. Threads are protected from corrosion and rust, and shock and vibration do not cause them to loosen.
How To Remove Loctite: Detailed Instructions
Bolts and screws are secured in their respective positions with the help of Loctite adhesives and threadlockers. Under pressure or during strenuous exercise, they keep joints from shaking and loosening.
- You can use the towel to wipe off dust and dirt from the bolt, nut, or screw you want to unscrew. Doing so will prevent fires.
- The Loctite bonded object and the heat gun should be at a distance of about 5 cm.
- Heat up the area with the heat gun. The surface should be heated quickly to avoid damaging it.
- Once the surface has been heated, move on to the next tools gradually.
- For removing the component, you will need a socket wrench set and a screwdriver.
- In a heated environment, Loctite adhesives break, making it possible to remove nuts and screws using ordinary hand tools.
- Heat or sweat will remove threadlocker from the area from which you wish to remove it.
- Applying steam to the joints can be very helpful. By weakening the adhesive, it allows the fastener to be removed. It’s that simple.
Be careful. Unless the proper removal methods are followed, removing it can be challenging due to the nature of the glue.
Comparative Cost Analysis
Loctite 262 vs. 271; is there a difference in price? In the United States, Loctite 262 and Loctite 271 cost similar amounts. Depending on where you buy it, a 10ml bottle of threadlocker will cost you between $13 to $20. The cost is likely to be the same whether you choose one or the other.
Loctite 262 vs. 271: which one do you pick?
Loctite 271 and 262 are the two types of red Loctite on hand. Which one should you choose? Luckily, if an application requires Loctite 262, then using 271 will not negatively affect it. Due to its same working temperature range, you do not have to worry about it bursting at high temperatures.
