Threads are essential for maintaining the structural integrity of many mechanical components. Due to their critical role, they can sometimes become damaged and require repair. Fortunately, you don't always need to replace an entire part—internal thread repairs can often be done efficiently with the right tools. In this blog post, we introduce two professional solutions: BaerCoil® and BaerFix®—two powerful options for fixing internal threads.
When it comes to DIY internal thread repairs, it's important to remember that precision and durability matter. Using improper materials or tools can lead to further damage. However, with BaerCoil® and BaerFix®, the process is simple, fast, and cost-effective, even for those without advanced experience.
BaerCoil® wire thread inserts are made from cold-formed wire with a diamond-shaped cross-section. This design ensures maximum strength while taking up minimal space, making them ideal for repairing internal threads in tight areas. They come in three types: free-running, screw grip (screw-locking), and NoTang (without tang). Each type has its own advantages, depending on the application.
The free-running version is available in various materials like stainless steel, Inconel, and bronze, offering flexibility for different environments. The screw grip type uses polygon-shaped turns to create a strong clamping force, which is especially useful in high-vibration settings. The NoTang version eliminates the need for a tang, simplifying the installation process.
To install BaerCoil® inserts, you’ll need a few basic tools: a twist drill, STI tap, countersink tool, installation tool, and a tang breaker. These tools are often sold in convenient sets, making the process easier for beginners.
For BaerFix® self-tapping threaded bushings, the key feature is their self-tapping mechanism. Unlike traditional inserts, these don’t require pre-cutting the thread—they cut their own as they’re installed. This makes them ideal for soft or low-strength materials where traditional methods might fail.
BaerFix® inserts come in different versions tailored for various materials. Some have cutting slots for easier machining, while others have cutting holes for more challenging materials. Installation is straightforward, requiring only a drill, a countersink, and an installation tool.
When choosing between BaerCoil® and BaerFix®, consider your specific needs. BaerCoil® is highly flexible and works well in a wide range of materials, including harder ones up to 750 N/mm². It’s great for general use. BaerFix® excels in softer materials, offering strong, precise connections due to its thick-walled construction and self-cutting design.
In summary, both systems are excellent choices for internal thread repairs. Whether you're working with soft materials or need a versatile solution, BaerCoil® and BaerFix® provide reliable, easy-to-use options. You can find both in the BAER online shop, ready to help you fix your threads quickly and effectively.
