Threaded inserts, also known as Helicoil inserts, are essential devices for professionals. They are used to repair or reinforce damaged or worn threads in materials such as metal or plastic. They act directly on the solidity of the tapped hole and your assembly by perfectly compressing themselves once inserted into the female (internal) threads of the tapped part.
Threaded inserts allow stronger threads to be created in new materials. They are a very useful tool in the fields of mechanical engineering, the automotive industry, aeronautics and many other fields involving the assembly of mechanical parts.
Helicoil thread inserts are available in 304 stainless steel. These spring-shaped inserts are inserted into a pre-drilled hole to form an internal thread.
With a larger outer diameter than that of the original hole, it efficiently reinforces the internal thread. Once in place, the thread insert becomes a new wear-resistant thread, capable of accommodating a bolt or a screw.
They are mostly used in materials with low shear strength, such as aluminium or aluminium-magnesium alloys.
In addition, Helicoil thread inserts allow you to:
Helicoil threaded inserts can be broken down into several different thread types (metric, UNC, UNF, BSF) that you can find in our numerous kits.

Why use threaded inserts?
All our threaded inserts are available in:
Installing a threaded insert is both simple and cost-efficient - all you have to do is follow a few basic steps. We offer a wide range of manual and automatic tools to help you successfully install your thread inserts.
Step one: drilling the tap drill hole
For drilling, use a high-quality standard twist drill. Before starting, remember to chamfer at 90° and to carefully deburr the surface for optimal preparation.
Second step: tapping
To create a hole for the threaded insert, we recommend using specific taps suitable for the system and the thread.
Thanks to our system of tapping via material removal, you can get a perfectly "clean" thread, without any chips.
Last step: installing the threaded insert
You can insert the threaded bush using either a manual installation tool or an automatic installation tool.
We have a special tool for removing threaded inserts: threaded insert removal tool
In order to remove a threaded insert, we recommend using an extraction tool. Start by making sure you have the necessary equipment: an extraction tool that matches the diameter of the insert, a key or screwdriver depending on the model of the tool, and, in some cases, lubricant to make the process easier.
Before doing anything, identify the threaded insert that needs to be removed, checking its dimensions and general condition.
This will enable you to choose a tool with the right dimensions. You should also check the bore hole for any damage.
You should then insert the tip of the extraction tool into the thread insert, making sure it clings to the coils without using force.
Twist the tool anti-clockwise in order to gradually remove the threaded insert in a "spiral" fashion from the hole.
If the insert is stuck, you can apply lubricant to remove it more easily.
Once the insert has been removed, check the bore hole for any damage and get rid of any residue with a compressed air duster or a wire brush.
