Loctite Threadlocker Red 271 is a permanent strength adhesive thread locker formulated to lock metal nuts and bolts from loosening due to vibration. Its moisture-resistant formula protects against leaks, rust and corrosion.
At the same time, it does make a great bond for large fasteners like those commonly used on heavy machinery, engines, and vehicles. This industrial-strength adhesive cures in only 10 minutes.
In under 24 hours, it cures completely to form the ultimate seal that resists temperatures up to 500°F. It’s ideal for all nuts and bolts up to 1 inch.
This design removes the requirement for additional hardware such as lock nuts or washers, making it an efficient option for rugged applications.
Prevents Loosening and Vibration Resistance
Loctite Threadlocker Red 271 provides an effective remedy for preventing metal fasteners from loosening under the stress of extreme conditions. It’s excellent at preventing nuts, bolts, and fasteners from loosening. Nothing short of an earthquake will shake them loose!
In applications such as automotive engines or other heavy equipment, constant movement is a harsh reality that cannot be controlled. This green threadlocker absolutely prevents any loosening that would ever endanger safety or performance. Their high-strength formula makes quick work of even the highest-vibration environments.
It is especially effective in high temperature applications where other locking mechanisms may become ineffective. Rather than lock washers or double nuts, this adhesive prevents loosening and vibration resistance without the need for additional hardware. Forming a lasting bond reduces assembly time.
Additionally, it helps to prevent parts from falling out of calibration over time. I have found it to be particularly effective at locking fasteners on equipment that experiences a lot of cyclic motion. Even after a few hundred dips and spills, I’m confident that bond isn’t going anywhere.
It’s an ideal, permanent locking and sealing fix for threaded connections, making it a great solution for projects that need to stand the test of time.
Moisture and Corrosion Protection
Loctite Threadlocker Red 271 is a true leader in the category, with its moisture-resistant formula forming a reliable seal to guard against leaks and rust. This is an important feature that makes it uniquely advantageous for components commonly subject to moisture or corrosion. If you’re tuning up lawnmowers or removing seized fasteners on water pumps, you’ll be amazed at its extreme wear and moisture protection.
It’s elastic, which means it doesn’t fatigue with repeated stretching! It’s the equivalent of putting a double layer of insurance on your work. The corrosion protection it provides makes a dramatic difference in fastener longevity. Rust can eat away at metal connections, resulting in expensive repairs or replacements.
By preventing that, this threadlocker protects the longevity of your projects. I’ve even used it on alternators and had the fasteners remain tight and rust-free after extended use for a period of months. It’s the perfect solution for applications in harsh, corrosive environments.
Engines, machinery, or anything exposed to heat, vibration, and moisture can really benefit from this added protection.
Permanent Seal with Heat-Removable Option
Loctite Threadlocker Red 271 provides an ultra-reliable permanent seal that holds parts securely in place while offering extra protection against theft and tampering. This design feature is particularly advantageous for mission-critical applications. It’s especially important for applications where the failure of bolts or fasteners would be dangerous, such as in mechanical systems or structural components.
The adhesive creates an extreme bond that handles impacts, shock, high stress, and environmental conditions. This provides long-term peace of mind, as frequent monitoring or maintenance isn’t required.
What gives this product its versatility is its heat-removable feature. Though it creates a permanent seal, using an application of high heat up to 500°F will let you easily take apart pieces when the time comes. This is a great pragmatic solution for keeping or improving elements that may otherwise be considered intractably fixed.
Whether you’re on automotive suspension systems or heavy-duty machinery, you can be assured of its superior hold. If that isn’t enough, when you do need to remove it, you have the ability to easily and cleanly remove it.
I’ve used it on structural bolts and on auto frames, and it’s worked perfectly.
Fast Setting and Curing Time
Loctite Threadlocker Red 271 sets fast, in only 10 minutes. That speed combined with its bonding capabilities make it ideal for fast repairs and speedy fabrication in your projects. When you’re tightening bolts down on an engine or tightening down nuts on big iron equipment, you’ll be glad for the quick set time.
It gets you set up and moving without the wait! That fast setting is ideal for all those times you just need to get past it fast. It saves you time in the field during assembly or repairs, maximizing your productivity.
Another benefit is the 24-hour cure time, which provides a strong, permanent bond. Once cured, it’s able to withstand high stress and vibration making it dependable for even the most extreme applications. This full cure time offers optimal durability while keeping convenience in mind.
In either case, you can have peace of mind in the knowledge that the bond will endure. Whether you’re a busy contractor or a do-it-yourselfer, this feature saves you valuable downtime so you can return to work quickly with peace of mind.

How to Apply Permanent Thread Lock Glue Effectively
Surface preparation is the key first step to making sure your glue will form a solid bond. Dirt, grease, or old adhesive can cause adhesion failure. A clean cloth and some degreaser or rubbing alcohol are effective for cleaning off residue.
Don’t rush this step, a clean surface is crucial for a strong bond. When you’re working with automotive bolts that are exposed to oil, a simple rag isn’t enough. Rather, cleaning up those bolts really well helps them do their job the best.
When it comes to the final product, how much glue you use can make a huge difference. The trick is to apply a very thin, uniform layer on the exposed threads. A common issue with over-applying is that it will drip or just make a mess, wasting product and making assembly more difficult.
For example, I’ve learned from experience that a single drop is almost always sufficient for bolts less than 1/2 inch in diameter. If your threads are larger, they’ll require a bit more.
Joining the pieces together right away after applying the glue hardens the bond. Once assembled, keeping the joined pieces still for the suggested curing period guarantees full strength.
Loctite Threadlocker Red 271 will take about 24 hours to cure completely at room temperature. Take the time to plan if those fasteners are on critical machinery or equipment! Allowing the adhesive to cure completely stops the loosening from happening again—even when exposed to extreme vibrations.
