Threads are essential for maintaining the structural integrity of various components. When these threads get damaged, it’s understandable to feel concerned about replacing the whole part. But here’s some good news: repairing internal threads doesn’t have to be complicated or costly. With the right tools, it can be a straightforward process, even for beginners. Today, we’re going to explore two professional solutions for internal thread repair: BaerCoil® and BaerFix®.
### DIY Solutions for Internal Thread Repairs
Can you fix internal threads using everyday household items? While it might seem tempting, precision and durability are critical when it comes to threads. Therefore, we recommend steering clear of non-specialized materials or tools for this task. Luckily, BaerCoil® and BaerFix® offer a quick, cost-effective, and user-friendly approach to repairing internal threads—so even those new to this kind of work can manage it effectively.
### Repair Internal Threads with BaerCoil® Wire Thread Inserts
BaerCoil® thread inserts are crafted from wire that’s cold-formed into a diamond-shaped cross-section during manufacturing. This design provides maximum stability while taking up minimal space, making it ideal for safely and efficiently repairing internal threads.
#### Types of BaerCoil® Wire Thread Inserts
These inserts come in three main varieties, each with its own unique characteristics:
- **Free-Running**: Available in several materials like Stainless Steel V2A for general purposes, Stainless Steel V4A for enhanced corrosion resistance, Inconel X750 for high thermal resistance, and Bronze, which is non-magnetic and has excellent electrical conductivity.
- **Screw Grip (Screw-Locking)**: Features one or more polygon-shaped turns that apply a clamping force on the screw flanks when repairing an internal thread. This ensures exceptional strength, especially under shock and vibration conditions. However, this type requires the use of high-strength screws.
- **NoTang**: Designed without a tang, reducing one step in the installation process.
#### Tools Required for BaerCoil® Internal Thread Repairs
BaerCoil® inserts can be installed manually or with machinery. First, you’ll need a twist drill bit and the appropriate STI tap for screw thread inserts. If you plan to countersink the core hole of the receiving thread, a countersink tool will also be necessary. Then, you’ll use the installation tool. If you’re using a stationary drill machine, ensure you have the specific machine installation tool. Finally, a tang breaker will complete the repair process.
Here’s a simple step-by-step guide:
1. Drill out the damaged thread or pre-drill the core hole.
2. Cut the receiving thread into the drilled hole.
3. Place the BaerCoil® thread insert on the installation tool or machine installation tool and screw it into the receiving thread.
4. Unscrew the tool, leaving the wire insert inside the thread.
5. Break the tang using a tang breaking tool.
All the tools and inserts needed for internal thread repairs are available in convenient sets and assortments, simplifying the process for you.
### Repairing Internal Threads with BaerFix® Self-Tapping Thread Inserts
One standout feature of BaerFix® thread inserts is their self-tapping mechanism. Unlike other methods, there’s no need to pre-cut the thread; the threaded bush creates its own thread as it’s inserted into the material.
#### Types of BaerFix® Thread Inserts
BaerFix® thread inserts come in different versions:
- Made from case-hardened steel, stainless steel, or brass with cutting slots for easy to medium machinable materials.
- Made of case-hardened steel or stainless steel with cutting holes for materials that are easy to difficult to machine.
- Made from case-hardened steel with cutting holes specifically for spark plug threads.
#### Tools Needed for BaerFix® Internal Thread Repairs
For installing BaerFix® thread inserts, you’ll need a suitable twist drill and countersink for preparing the locating hole. The actual installation is performed either by hand using a special installation tool or with a machine installation tool if you opt for a stationary drilling machine. Convenient sets and assortments containing all the necessary parts are available in our online shop.
#### Step-by-Step Installation Process
1. Drill out the damaged thread or pre-drill the core hole.
2. Turn the BaerFix® thread insert onto the installation tool or machine installation tool.
3. Screw in the BaerFix® thread insert with the installation tool.
4. Unscrew the installation tool again.
### Comparing BaerCoil® and BaerFix®: Which Is Right for You?
Both BaerCoil® and BaerFix® are excellent options for repairing internal threads at home, but they cater to slightly different needs.
BaerCoil® wire thread inserts are incredibly versatile and can adapt to varying loads, evenly distributing forces across all threads to increase load-bearing capacity. Although installing them requires a bit more effort because you need to pre-cut the thread, they work well with materials up to approximately 750 N/mm².
On the other hand, BaerFix® thread inserts excel in soft materials and those with low shear strength. Their thick walls provide significant contact with the receiving material, allowing them to create nearly zero tolerance connections, which results in exceptionally strong threaded joints. However, BaerFix® reaches its limit with materials over 400 N/mm² and may require more space due to its thick walls, limiting its application in certain scenarios.
In summary, whether you need a flexible all-around solution like BaerCoil® or something specialized for soft materials like BaerFix®, both systems are accessible through the BAER online shop. Choose based on your intended use, and enjoy a reliable repair experience!
