Thread Repair Kits, UNC 3/4 - 1,5D

Your V-COIL Thread Repair Kit UNC 3/4 - 1.5D – The Pro Solution for Strong Threads

Got a thread problem with your project? No need to worry! The V-COIL Thread Repair Kit UNC 3/4 - 1.5D is your indispensable partner when it comes to quickly, reliably, and permanently repairing or strengthening threads. With this high-quality set from VÖLKEL, you'll create high-strength, durable threaded connections that can even surpass the original quality. Ideal for your workshop, maintenance, assembly, or if you need to salvage scrap parts.

What this kit can do & where you use it: This thread repair kit is specifically designed to permanently restore damaged internal threads or to create new, extremely resilient threads in softer materials such as aluminum, magnesium, cast iron, plastics, or other light metals. No matter where you need a reliable threaded connection, the V-COIL kit makes it possible!

Typical applications for you:

• Thread Repair: Quickly and effectively repair worn, damaged, or stripped threads in your components and machines.

• Thread Reinforcement/Armoring: Create robust threads in low shear strength materials to increase the load-bearing capacity and longevity of your connections.

• Scrap Recovery: Salvage valuable workpieces with faulty threads, saving costs and valuable resources.

• Assembly & Small Batch Production: Perfect for recurring tasks where you require precise and durable threads.

Your advantages with the V-COIL Thread Repair Kit:

• Higher Thread Load Capacity: After repair, the installed thread inserts, thanks to their excellent material properties, offer significantly higher tensile strength and shear strength than the original thread. Your connections will hold up better!

• Corrosion and Temperature Resistance: The thread inserts made of stainless steel guarantee excellent resistance to corrosion and high temperatures.

• Complete Solution: The kit contains all the necessary tools (STI tap, hand installation tool with retaining ring) and enough thread inserts so you can get started right away.

• Long Lifespan: Extend the lifespan of your threaded connections and reduce your maintenance efforts.

• Practical Packaging: The kit comes in a robust plastic case – perfect for organized storage and easy transport.

What's included for you:

• 1x STI Tap, ForD, HSS-G, UNC 3/4 x 10 (VÖLKEL 03114): A special tap to prepare the perfect receiving thread for your thread inserts. Made from High-Speed Steel (HSS-G) for optimal drilling performance and durability.

• 1x Hand Installation Tool with Retaining Ring, No. 20 (VÖLKEL 08020): This allows you to precisely and easily screw in the thread inserts by hand.

• 5x Thread Inserts – Type S – Free Running UNC 3/4 x 10 – 1.5 D: High-quality thread inserts made of stainless steel for a permanent repair.

What do the technical details mean for you?

• Nominal Size: UNC 3/4 x 10:

  • UNC (Unified National Coarse): This is an American thread standard for coarse threads. It defines thread profiles, pitches, and diameters. UNC threads are widely used in the USA and in countries that adhere to American standards.

  • 3/4: This value indicates the nominal diameter of the thread in inches (here 3/4 inch).

  • 10: This is the number of threads per inch (here 10 threads per inch).

• 1.5 D (Thread Length):

  • The "1.5 D" designation for thread inserts stands for the nominal length of the thread insert. "D" represents the nominal diameter of the thread to be repaired. In this case, the length of the thread insert is 1.5 times the nominal diameter of 3/4 inch. This ensures an optimal engagement length and load-bearing capacity for your new thread.

• DIN 8140:

  • DIN 8140 is a German industrial standard that specifies coiled wire thread inserts (often known as Helicoil or V-COIL). It defines dimensions, tolerances, materials, and testing procedures for these types of thread inserts to ensure their interchangeability and functionality. So you can be sure everything fits and works!

• Tolerance ISO 2 (6H):

  • Tolerance: This describes the permissible deviations from the nominal dimensions of a thread. Precise tolerance is crucial for the fit and function of your threaded connection.

  • ISO 2 (6H): This is an international tolerance class for internal threads.

    • ISO 2: Represents a medium tolerance class used in most general applications, ensuring a good fit.

    • 6H: Is the specific ISO designation for the tolerance class of an internal thread. The "6" refers to the tolerance quality (the smaller the number, the tighter the tolerance), and "H" indicates the fundamental deviation for internal threads (H stands for "Hole" and means that the lower deviation of the thread is equal to the nominal size, allowing for an easy fit).

• Thread Inserts Type S - Free Running:

  • This describes the type of thread insert. "Type S" means it's a standard thread insert. "Free running" (also known as "Standard" or "Free Running") means that after installation, the thread inserts form a conventional internal thread through which a screw can be freely turned without additional friction or clamping. They provide a pure threading function without self-locking properties.

Conclusion: With the V-COIL Thread Repair Kit UNC 3/4 - 1.5D, you're investing in a professional tool that helps you extend the lifespan of your components, minimize downtime, and maximize cost-efficiency. An essential kit for anyone who values precise and durable threaded connections.
