Threads play a crucial role in maintaining the structural integrity of many mechanical components. Given the critical nature of their function, it's not uncommon for threads to become damaged over time. Fortunately, repairing internal threads doesn’t always mean replacing the entire part. With the right tools and techniques, you can restore the functionality of damaged threads efficiently. In this post, we’ll introduce two professional solutions: BaerCoil® and BaerFix®, both designed to make internal thread repairs quick, reliable, and easy.
When it comes to DIY internal thread repair, it’s important to understand that using improper tools or materials can lead to further damage. Precision and durability are key when working with threads, which is why we recommend using specialized products like BaerCoil® and BaerFix®. These systems are designed for ease of use, making even complex repairs accessible to beginners.
BaerCoil® wire thread inserts are made from cold-formed wire with a diamond-shaped cross-section. This design offers maximum strength while taking up minimal space, making them ideal for repairing internal threads without compromising the structure of the component. They come in three main types: free-running, screw grip (screw-locking), and NoTang (without tang). Each variant has its own advantages depending on the application. For example, the screw grip type provides exceptional clamping force, making it perfect for high-vibration environments, while the NoTang version simplifies installation by eliminating one step.
To install BaerCoil® inserts, you’ll need a few basic tools: a twist drill bit, an STI tap, a countersink tool if needed, an installation tool, and a tang breaker. All these tools are available in convenient sets, so you don’t have to source them individually. The installation process involves drilling out the damaged thread, cutting a new thread into the hole, inserting the BaerCoil® insert, and breaking off the tang once it’s in place.
On the other hand, BaerFix® self-tapping threaded bushings offer a different approach. Unlike BaerCoil®, they don’t require pre-cutting of the thread. Instead, the threaded bushing itself cuts the thread as it is inserted into the material. This makes the process faster and more efficient, especially when working with softer materials. BaerFix® inserts are available in various materials and configurations, including versions with cutting slots or holes, making them suitable for a wide range of applications.
Both BaerCoil® and BaerFix® have their strengths. BaerCoil® is ideal for most general-purpose repairs due to its flexibility and high load-bearing capacity, while BaerFix® excels in soft or low-shear-strength materials where a strong, secure connection is essential. Choosing between the two depends on your specific needs and the type of material you're working with.
Whether you're a professional mechanic or a DIY enthusiast, both systems provide an effective solution for internal thread repair. You can find both BaerCoil® and BaerFix® in the BAER online shop, ready to help you restore damaged threads quickly and efficiently.
