Team Corally LOCKIT 400 Screw Fix Hard Green Threadlock Compound 20g C-13096

Overview

The Corally LOCKIT 400 Screw Fix Hard Green is a professional-grade threadlock compound designed for RC enthusiasts, hobbyists, and serious modellers who demand reliability from their models. Whether you're building an RC car, truck, buggy, or any other RC vehicle, this permanent locking adhesive ensures that your threaded fasteners remain secure under the toughest conditions. The vibrations, shocks, and constant movement inherent to RC driving can cause screws, nuts, and bolts to gradually loosen over time, leading to potential failures, component damage, and costly repairs. This is where Corally's LOCKIT 400 becomes an essential part of your RC toolkit in the UK and beyond.

Made in Europe with precision engineering, the Corally LOCKIT 400 is specifically formulated to provide permanent fixation of threaded fasteners whilst also offering rust and corrosion protection. The hard-setting formula means once cured, your connections are locked solid, providing the peace of mind that your RC model will stay together during high-speed runs, jumps, landings, and competitive racing. This 20-gram bottle provides excellent value, giving you plenty of threadlock compound for multiple projects and ongoing maintenance of your RC collection, whether you're a casual weekend basher or an experienced competitor.

The instant curing action of this threadlock eliminates the need for lengthy waiting periods between assembly stages. This makes it ideal for hobby builders who want to progress quickly through their projects without compromising on the security of their builds. The product cures only when confined in the absence of air between close-fitting metal surfaces, ensuring effective bonding without waste or messiness.

Key Features

• Permanent Fixation — This threadlock compound creates a permanent bond once cured, meaning your screws, nuts, and bolts will not gradually loosen under vibration and shock, which is critical for RC vehicles that experience constant movement and impact.
• Prevents Vibration Loosening — One of the most common issues in RC hobby cars and trucks is fasteners working loose due to the constant vibration and shock loads experienced during driving; this compound actively prevents that problem from occurring.
• Rust and Corrosion Protection — Beyond just locking fasteners, the Corally LOCKIT 400 protects threaded components from rust and corrosion, extending the lifespan of your metal parts and maintaining structural integrity over time.
• Instant Curing Action — The rapid curing formula means you can progress with your build quickly without having to wait extended periods for the adhesive to harden, speeding up assembly and maintenance workflows.
• Hard Formula — The hard-setting variant ensures a solid, permanent bond that won't flex or move once cured, providing maximum security for critical fasteners in high-stress applications.
• European Manufacturing — Manufactured in Europe to strict quality standards, this compound meets professional specifications and delivers consistent, reliable results across all your RC projects.
• 20-Gram Bottle — The generous 20-gram size provides excellent value for money, giving you enough compound for multiple models and ongoing maintenance of your existing RC collection without frequent repurchasing.
• Easy Application — The liquid formula applies directly to threaded surfaces, making application straightforward for both experienced modellers and those new to using threadlock compounds on their RC vehicles.

Technical Performance

The Corally LOCKIT 400 Screw Fix Hard Green operates on a straightforward but highly effective principle: it cures in the absence of air between close-fitting metal surfaces. This means when applied to threaded fasteners that are then tightened into place, the compound immediately begins bonding as the air is displaced and the thread contact surfaces are brought together. The hard-setting formula creates a permanent, rigid bond that prevents any rotational movement of screws, bolts, and nuts, effectively eliminating the primary cause of fastener failure in RC models. The compound's ability to protect against rust and corrosion is particularly valuable for RC vehicles that may be used in damp conditions or stored for extended periods. The green colour of the compound provides clear visibility during application, allowing you to verify coverage and prevent over-application. This is a standard-strength threadlock suitable for permanent applications where fasteners should never be removed or only removed with significant effort. The instant curing action means there's minimal waiting time between applying the compound and being able to proceed with your build, making this an efficient choice for both initial assembly and ongoing maintenance of your RC car, truck, buggy, or other RC hobby vehicles.

Frequently Asked Questions

• What is threadlock and why do I need it for my RC car? — Threadlock is a liquid adhesive compound that creates a permanent bond between threaded fasteners (screws, nuts, bolts) and prevents them from loosening due to vibration and shock. In RC vehicles, constant movement and impact forces cause fasteners to gradually work loose, which can lead to parts falling off, misalignment, or complete component failure. Using threadlock on critical fasteners ensures your RC model stays together securely during driving, jumping, and racing.
• Is the Corally LOCKIT 400 suitable for beginners? — Yes, absolutely. Threadlock is one of the simplest maintenance products to use. You simply apply a small drop to the threads before assembling the fastener, then tighten it normally. The compound does the rest. Even beginners building their first RC model will find this straightforward and beneficial for keeping their model secure.
• How long does the Corally LOCKIT 400 take to cure? — The Corally LOCKIT 400 features instant curing action, meaning it bonds quickly once the threaded fastener is tightened in place and air is displaced from the contact surfaces. You don't need to wait extended periods like with some other adhesives, allowing you to continue with your build or maintenance immediately.
• Can I remove fasteners that have threadlock applied? — The Corally LOCKIT 400 is a hard-setting formula designed for permanent fixation. Fasteners bonded with this compound require significant effort and tools to remove, which is the intended purpose. If you need to remove fasteners regularly, you may want to consider using a medium-strength threadlock instead, but for permanent applications like shaft locking and critical bearing retention, this hard formula is ideal.
• What fasteners can I use threadlock on? — Threadlock can be used on any threaded fastener including screws, nuts, bolts, threaded shafts, and bearings. The Corally LOCKIT 400 is particularly effective on metal-to-metal connections. Apply it to fasteners that you want to remain permanently secured and protected from vibration loosening.
• Is the Corally LOCKIT 400 made to professional standards? — Yes, this product is manufactured in Europe to professional specifications and quality standards. The formula is proven in demanding applications, making it suitable not just for casual hobbyists but also for competitive RC racing where reliability is paramount.
• How much does a 20-gram bottle cover? — A 20-gram bottle is generous and will treat many fasteners. Since you only apply a small drop per fastener, a single bottle will provide threadlock for numerous RC models or extended maintenance of an existing collection without requiring frequent repurchasing.
• Does the green colour matter? — The green colour is simply a visual indicator helping you apply the compound accurately. It provides clear visibility so you can verify that fasteners have been treated and prevent over-application. Different colours typically indicate different threadlock strengths (blue is usually removable, red is permanent), so the green hard formula is this specific Corally product variant.
