Loctite 263 vs. 272: What’s The Difference?
After testing these two red roosters out myself, here’s the scoop. 263 flows easier and sets up faster than the thicker 272. We’re talking minutes rather than hours to reach full strength. So 263’s your new best friend for smaller fasteners that need a quick grip.
Loctite 263 vs. 272: Specs & Uses
If you need to lock down large bolts and can wait a few hours for full strength, 272’s your huckleberry. But if you’re working with smaller parts or need a faster fix, go with 263. Both form strong, stubborn bonds that you can count on. You really can’t go wrong with either of these Red Hot Chili Peppers.
My Hands-on Test: Loctite 272
✅Pros
Not only did it meet the specifications and cure time as advertised, but it also provided excellent value for the money.
Performance
Now, let’s talk about the performance. Loctite 272 really holds bolts in place securely. In fact, I used it to fix the muffler of my bike by applying it to the screws, and it did a fantastic job. The adhesive cured within the expected time frame, and I was impressed with its reliability.
While the Loctite 272 generally holds fairly well, I did encounter a specific issue with my turbocharger compressor nut. After using the Klean N’ Prime and allowing a 48-hour set time, the nut secured by Loc-tite came loose when a hose blew off the compressor. This caused the turbo to boost at much higher levels, generating more heat than normal. I had to rebuild the turbo and gave Loctite 272 another try, this time allowing a longer 72-hour set time before heat cycling. Since then, the threaded connection has remained tight, and I haven’t experienced any further issues.
Locked Everything Firmly
Loctite is the go-to brand for people who value the longevity and stability of their engines. I’ve used standard red Loctite in the past, but this Loctite 272 I tried was a bit slower to set. However, after waiting for 24+ hours, it locked everything firmly, just as indicated in the product listing. I must admit, I had initial concerns, but it eventually proved its effectiveness.
Value for Money
Now, let’s talk about the price. At over $20, I had high expectations for Loctite 272, and I’m happy to report that it lived up to them. While it may seem expensive compared to school paste, it’s important to invest in reliable products like this one.
❌Cons
However, I want to provide an update based on my experience. Unfortunately, not everyone may have the same positive outcome. A fellow DIY enthusiast had a different experience with this Loctite version. They mentioned that it took over 30 hours for the adhesive to set, which was quite disappointing. They even compared it to school paste, suggesting that it was equally effective. So, it’s worth considering other options and doing some research before making a purchase.
FAQ
Q: What is the maximum temperature range for Loctite 272?
A: According to the specifications provided by Loctite, Loctite 272 is designed for extreme duty applications with high temperatures. It is suitable for fasteners up to 1-1/2″ in size and can withstand temperatures ranging from -65 degrees Fahrenheit to 450 degrees Fahrenheit. It can be removed using heat and hand tools. The application time is 60 minutes, full cure time is 24 hours, and it can be applied at a temperature of 72 degrees Fahrenheit.
Q: Is it supposed to have a thick consistency? I previously used the 271 version (loctite 263 vs 271
), which was liquid and flowed smoothly on the threads. However, this one doesn’t seem to have the same properties…
A: The 272 variant that I have doesn’t have a thin and runny consistency like the 271 version. It adheres well to the threads.
Q: Will Loctite 272 work well with my AR-15’s muzzle brake?
A: Absolutely! Just remember that if you ever want to remove your brake, you can use a heat gun to warm the Loctite, making removal easier.
Q: Can I use it on both plastic and steel threads?
A: Loctite 272 is specifically designed for high strength in high-temperature environments (up to 400 degrees Celsius). It is a threadlocker, not a glue. Using it on plastic threads may prevent the screw from being removed intact. It is intended for use on metal threads.
Q: Can I use Loctite 272 if the bolts will come into contact with diesel fuel after it has fully cured?
A: I’m not sure, as I haven’t tested it on anything exposed to diesel yet.
Q: Is this formula suitable for small screws?
A: It is suitable for threads of any size that you want to stay securely in place! After 24 hours, you will need to apply heat to remove it.
Q: Is this the fast-setting formula?
A: While the product does not explicitly state that it is fast-setting, based on my experience using it to attach gas blocks on rifle barrels, the screws set immediately after applying the red 272 and torquing them. Additionally, this formula is highly resistant to heat.
Q: Between the 271 and Loctite 272, which one is better for BBQ grill bolts?
A: Just apply a single drop of Loctite 272 in the thread, and voila, it will never come loose. You can remove it if needed, but it provides excellent grip.

My Hands-on Test: Loctite 263
✅Pros: Loctite 263
One of the reasons I love using Loctite is its strength and resistance to higher temperatures. It’s a must-have for any DIY project involving threaded connections that you want to keep securely fastened. The red Loctite I’ve used has proven to be even stronger and more temperature-resistant than the blue variant.
Removability
Now, let’s talk about its “removability” factor. Despite its reputation for being permanent, I’ve found that with a bit of effort, it can still be removed even after fully curing. Don’t worry; you won’t need any special tools. Just channel your inner strength and give it a good twist.
Longevity
The longevity of this small tube is truly impressive. It lasts for years, which is a testament to its quality and effectiveness.
Versatility
What I appreciate about Loctite is its versatility. Unlike some alternatives, this product works well even on slightly oily fasteners, eliminating the need for an additional primer. It’s a convenient time-saver that doesn’t compromise on performance.
Specific Applications
Moving on to specific applications, I had a recent experience securing my catalytic converter (CAT) after an attempted theft. I used Loctite on the clamp screw threads, and let me tell you, it passed my tests with flying colors. I couldn’t remove the screws unless the CAT and screws were heated, making it an excellent choice for added security.
While we’re on the topic of applications, I must mention that Loctite is an excellent thread locker. It lives up to its claims and performs exactly as expected. For maximum strength, I highly recommend letting it cure for 48-72 hours.
❌Cons: Loctite 263
Loctite’s strong odor can be off-putting for some individuals, particularly those with sensitivities to strong chemical scents. It’s advisable to use the product in a well-ventilated area to minimize any potential discomfort.

Hi, does the bottle come filled with liquid? Is it more than half full?
Henkel intentionally uses a large bottle so that it can be filled with nitrogen. This helps keep the compound in a liquid state. If there is no air present in the bottle, the compound would dry and solidify. The same explanation can be found online. However, the liquid content is as described: 50ml in a 250ml bottle.
Can I use Loctite 272 for my AR-15's anti-lock trigger pins and front handguard rail screws?
DO NOT use Loctite 272 on your trigger pins or handguard screws! This Loctite is a high-strength formula designed for high-temperature areas, such as set screws on a gas block. It is extremely difficult to remove. Instead, use Blue Loctite for your handguard screws. I strongly advise against using any Loctite on components related to your fire control system.
