Screw Thread Insert

Screw Thread Inserts, also known as helicoil inserts or threaded inserts, are fastening devices used to create strong and durable threads in materials that may not have sufficient strength to support a threaded hole directly. They are commonly used in applications where the original threads have been damaged or stripped, or in materials that are prone to wear and tear.

Screw Thread Inserts are typically made of stainless steel or other high-strength materials. They consist of a coiled wire with internal threads that match the desired thread size and pitch. The insert is inserted into a pre-drilled hole, and as it is screwed in, it expands to grip the surrounding material. This creates a secure and reliable threaded connection.

These inserts provide several benefits, including:

1. Increased strength: Screw Thread Inserts distribute the load over a larger area, increasing the strength and load-bearing capacity of the threaded connection.

2. Improved thread durability: By using a Screw Thread Insert, the original threads are protected from wear and tear, extending the lifespan of the threaded connection.

3. Repair damaged threads: Screw Thread Inserts can be used to repair damaged or stripped threads, saving time and money compared to replacing the entire component.

4. Versatility: Screw Thread Inserts can be used in a wide range of materials, including metals, plastics, and composites.

In summary, Screw Thread Inserts are fastening devices used to create strong and durable threads in materials that may not have sufficient strength to support a threaded hole directly. They provide increased strength, improved thread durability, and the ability to repair damaged threads.
