V-COIL Wire thread insert Free running type S UNx8 1.3/8 x 8 - 1.5 D (5 pcs.)

Areas of application:

• Thread Repair: Ideal for restoring damaged or worn threads to regain original strength and functionality.
• Thread Armor Plating: Creates high-load-bearing internal threads in materials with low shear strength, such as aluminum, magnesium, and plastics.
• Scrap Salvage: Allows for the cost-effective repair of scrap components that would otherwise have to be discarded due to damaged threads.

Benefits:

• High-Quality Material: Made from austenitic stainless chrome-nickel steel wire with a precision profile for increased resistance to corrosion and high temperatures.
• Spring-like Form: The special shape ensures a strong and permanent thread connection that is often more durable after repair than the original thread.
• Compact Design: Can be installed into existing constructions without extensive preparatory work.
• Secure Hold: The radial pressure between the coils and flanks of the tapped hole ensures that the thread insert remains securely in position.

The installation of a V-COIL wire thread insert is a simple, four-step process:

1. Drilling: Use a standard twist drill to drill out the damaged thread. Pay attention to the correct drill diameter according to the V-COIL system specifications for your nominal size (UNx8 1.3/8 x 8).
2. Tapping: Use a matching V-COIL tap to cut a new thread into the prepared hole. This tap is specially matched to the exact tolerances for the thread insert.
3. Installation: Screw the V-COIL thread insert into the newly cut thread using the appropriate V-COIL installation tool. Ensure a uniform feed until the insert is fully seated below the surface of the component.
4. Tang Break-off: After installation, use a tang break-off tool to break off the driving tang located at the end of the thread insert. The insert is now finished and ready for use.

1. What is a free-running wire thread insert?
A free-running wire thread insert, also known as a helical coil insert, is a spiral-shaped insert that is screwed into a larger thread in a component. It forms a new, more stable internal thread in the original size. "Free-running" means it has no locking feature and is suitable for applications where the thread needs to be continuous.

2. Why should I use a wire thread insert?
Wire thread inserts are used to repair threads that are damaged, worn, or incorrectly cut. They can also be used preventively in soft materials such as aluminum or magnesium to increase thread strength and prevent wear.

3. Is the repair with a V-COIL wire thread insert stronger than the original thread?
Often, yes. The V-COIL wire thread insert distributes the load more evenly across the thread flanks, resulting in higher load-bearing capacity and resistance to wear and corrosion than with a standard thread in the same material.

4. What tools do I need to install this thread insert?
For the installation of this thread insert, you will need a matching V-COIL tap, a V-COIL installation tool, and a tang break-off tool. These tools are specially designed to match the V-COIL thread inserts to ensure correct installation.

5. How do I choose the right length for the thread insert?
The length of the thread insert is specified as a multiple of the nominal diameter (D). A 1.5 D length, as with this product, means that the insert has 1.5 times the length of the nominal diameter. The correct length depends on the thickness of the component and the desired load-bearing capacity.
