What is the difference between Rotating coil and threaded insert?
Rotating coil and threaded inserts are both used to repair or reinforce threaded holes, but they differ in their design, application, and installation methods. Here is a breakdown of the differences between the two:
Helicopter Coil:
Design:
Rotating coil is a wire thread insert made from coiled wire shaped like a spring. It is designed to be inserted into a pre-drilled hole to create a new internal thread.
Installation:
To install a helical coil, a hole is drilled and tapped to a specific size. The Rotating coil is then inserted using a special installation tool. The coil expands to fit the hole and provides new threads for the screw or bolt.
Application:
Rotating coil are often used in applications where the original threads have been stripped or damaged, especially in softer materials such as aluminum or magnesium. They are also used in high stress applications due to their ability to spread the load.
Advantages:
Rotating coil can be used to repair threads in a variety of materials and provide strong, durable threads. They are lightweight and can be used in tight spaces.
Threaded Inserts:
Design:
Threaded inserts are solid metal or plastic inserts with internal threads designed to be permanently installed in pre-drilled holes. They come in various shapes, such as cylindrical or flanged.
Installation:
Installation typically involves drilling a hole, inserting a threaded insert, and then securing it in place using methods such as adhesives, press-fitting, or mechanical fastening.
Application:
Threaded Inserts have a wide range of uses including wood, plastic and metal. They are commonly used in furniture assembly, automotive applications and any situation where a strong, permanent thread is required.
Advantages:
Thread Inserts provide a strong and permanent solution for creating or repairing threads. In certain applications they can withstand higher loads and are less likely to strip than Rotating coil.
Summary of differences:
Material: Rotating coil are usually made of coiled wire, while threaded inserts are usually solid metal or plastic.
Installation Method: Rotating coil require tapping and special installation tools, while threaded inserts can be installed using a variety of methods, including adhesive or press-in.
Application: Rotating coil are often used to repair threads in softer materials, while thread inserts are used to create strong threads in a variety of materials.
Load Capacity: Threaded Inserts generally provide a stronger, longer lasting solution for high load applications compared to Rotating coil.
In summary, the choice between Rotating coil and threaded inserts depends on the specific application, material and load requirements.
