V-COIL Wire thread insert Free running type S M 14 x 1.25 - 2.0 D (50 pcs.)

• High-Quality Material: Produced from precision profiled austenitic stainless steel wire wound into a helical spiral for higher temperature and corrosion resistance.
• Increased Load Capacity: The repaired thread has a higher load capacity than the original thread due to the improved thread properties.
• Compact Design: The thread insert can generally be incorporated into existing designs where no previous provision has been made.
• Secure Hold: The position of the insert is maintained by the radial pressure action between its coils and the flanks of the tapped hole.
• Versatile Application: Ideal for repairing threads in engine casings, cylinders, gearboxes, and more.

Repairing a thread with the V-COIL system is a simple and effective process:

1. Step 1: Drill out the damaged thread. Remove the damaged thread with a drill bit. The drill bit size must match the V-COIL thread size.
2. Step 2: Tap the new thread. Use a special V-COIL tap to cut a new thread into the prepared core hole.
3. Step 3: Screw in the thread insert. Place the thread insert on the V-COIL installation tool and screw it into the tapped hole.
4. Step 4: Break off the tang. Once the insert is fully screwed in, break off the installation tang at the end of the insert. Your thread is now repaired and fully load-bearing.

Q: What is a "free running wire thread insert"?

A: A free running thread insert, often referred to as a wire thread insert, has a slightly larger diameter than the tapped hole when unloaded. This creates a spring action that guarantees high thread strength and securely locks the insert in the material. Once installed, the screw can run freely.

Q: What does the length designation "2.0 D" mean?

A: The length of the thread insert is specified as a multiple of the nominal diameter (D). For a nominal size of M 14, the length of the insert is therefore 2.0 x 14 mm = 28.0 mm.

Q: What does the tolerance designation "ISO 2 / 6H" mean?

A: The tolerance ISO 2 / 6H is an internationally recognized standard for metric internal threads. It ensures that the cut thread has a medium tolerance class and is therefore suitable for most applications and screws.

Q: How does the thread insert stay in the material?

A: Once screwed in, the spring-like wire of the insert exerts a radial pressure on the flanks of the tapped hole. This creates a tight, positive connection that provides increased torsional and tensile strength and secures the insert against loosening.

Q: For which applications is this V-COIL thread insert particularly suitable?

A: This insert is particularly useful for repairing threads in soft or brittle materials such as aluminum, magnesium, or plastic, as it significantly increases the thread's shear strength. It is often used in engines and gearboxes to restore damaged threads or to create new, highly load-bearing threads.
