Permanent Threadlocker for Grip Bushings, Front Sights, and Overtravel Screws

To begin with, Loctite 271 Red delivers a high-strength, permanent threadlocking solution designed to keep fasteners locked in place under extreme vibration and repeated stress. For this reason, gunsmiths and builders frequently rely on it for securing 1911 grip bushings, front sights, and trigger overtravel screws where movement simply cannot be tolerated.

In addition, each package includes a convenient 0.05 oz capsule, which provides the ideal amount for precision work. As a result, both professional gunsmiths and at-home builders can apply the product cleanly and efficiently without waste.

Locks and Seals Fasteners Under Extreme Conditions

Prevents Loosening from Vibration and Impact

First and foremost, Loctite 271 actively locks metal fasteners in place, even when exposed to constant vibration or heavy recoil. Because of this, it performs exceptionally well in high-stress environments such as firearms, engines, and industrial machinery.

Moreover, once applied, the compound fills the gaps between threads. Consequently, it eliminates movement that could otherwise lead to loosening, misalignment, or component failure over time.

Protects Against Rust and Corrosion

Moisture-Resistant Thread Sealing

Furthermore, Loctite 271 seals threaded connections against moisture intrusion. As a result, it helps prevent rust, corrosion, and fluid seepage that can compromise both performance and longevity.

At the same time, this sealing action removes the need for additional lock washers, lock nuts, or other mechanical retention methods. Therefore, you achieve a cleaner installation with fewer parts and greater reliability.

Permanent, High-Strength Bond

Designed for Critical, Non-Serviceable Applications

Most importantly, Loctite 271 cures into a permanent bond once fully set. Because of its high-strength formulation, it resists loosening even under severe operating conditions.

Additionally, removal requires heating the fastener to approximately 500°F (260°C). For this reason, it provides added security against tampering or accidental loosening in critical components where failure is not an option.

Fast and Efficient Application

Quick Set and Full Cure Times

Not only does Loctite 271 offer extreme holding power, but it also applies quickly and easily. Under normal conditions, it sets in approximately 10 minutes. Then, within 24 hours, it fully cures to deliver maximum strength.

Consequently, this fast cure time allows you to complete installations efficiently without long delays, making it ideal for both professional shops and DIY projects.

Engineered for Larger Fasteners

Heavy-Duty Formula for Demanding Applications

In addition, Loctite 271 is specifically formulated for fasteners up to 1 inch (25 mm) in diameter. Therefore, it excels in applications that demand a strong, long-lasting bond capable of handling substantial loads and repeated stress.
