Something about screw thread inserts

Screw thread inserts, also known as threaded inserts or helicoil inserts, are small metal components that are used to reinforce and repair threads in materials such as aluminum, magnesium, and other soft metals. These inserts are designed to provide a reliable and durable alternative to traditional threaded connections, which can be prone to stripping or wear over time.

The concept of screw thread inserts was first developed in the 1930s by the Heli-Coil Corporation. Since then, they have become a standard component in many industrial and manufacturing applications, from aerospace to automotive to electronics.

Screw thread inserts are typically made of high-strength materials such as stainless steel or titanium. They are available in a range of sizes and thread types to accommodate different bolt sizes and applications.

The installation process for screw thread inserts is relatively straightforward. First, a threaded hole is drilled in the material. Then, a tap is used to cut the threads for the insert. The insert is then installed by screwing it into the hole, where it locks in place with a series of spring-like coils.

One of the primary benefits of screw thread inserts is their ability to increase the strength and durability of threaded connections. Because the insert is made of a stronger material than the surrounding material, it can provide additional reinforcement and support for the threads. This can help prevent stripping or wear over time, which can lead to costly repairs or downtime.

Another advantage of screw thread inserts is their versatility. They can be used in a variety of applications, from repairing damaged threads to reinforcing new connections in soft materials. They can also be used to convert threaded holes from one size to another, which can be useful in situations where a different bolt size is required.

Overall, screw thread inserts are a valuable component in many industrial and manufacturing applications. Their ability to provide reliable and durable reinforcement for threaded connections can help improve the strength and longevity of equipment and machinery, while also reducing the risk of downtime and repair costs.
