What is a Heli-Coil insert and how does it work?
A Heli-Coil insert is a threaded insert used to reinforce and strengthen tapped holes. It consists of a coiled wire form with internal threads that match the desired bolt or screw size. The insert is installed into a pre-drilled or tapped hole, providing a durable and reliable threaded connection.
What are the benefits of using Heli-Coil inserts?
Heli-Coil inserts offer several benefits. They provide stronger assemblies by distributing loads evenly and compensating for lead and angle errors. They significantly increase thread life, even after repeated assembly and disassembly. Heli-Coil inserts have corrosion resistance, enhance design flexibility, eliminate stress on the parent material, minimize space and weight requirements, reduce total costs, and provide true clamping torque.
Are Heli-Coil inserts a permanent solution for threaded holes?
Yes, Heli-Coil inserts provide a permanent solution for reinforcing threaded holes. Once installed, they become an integral part of the assembly, offering durable and reliable threads. The inserts do not require any additional locking mechanisms and are designed to remain securely in place.
Are Heli-Coil inserts stronger than the original threads?
Yes, Heli-Coil inserts are generally stronger than the original threads they reinforce. They distribute loads more evenly, reducing stress concentrations. The flexibility of the insert allows for a balanced distribution of dynamic and static loads throughout the thread engagement, resulting in stronger assemblies.
Can Heli-Coil inserts be used in different materials, such as aluminum?
Yes, Heli-Coil inserts are compatible with various materials, including aluminum. They can be used in a wide range of applications involving different metals, alloys, and composite materials. Heli-Coil offers inserts in different materials, such as stainless steel and aluminum, to match specific material requirements and enhance compatibility.
