Custom Intervis® threaded insert
- 20 million threaded inserts with specific slots designed per year
- Co-designer of custom fasteners for 100 years and owner of the Intervis® brand
- From M2.5 to M16 and from 6 mm to 22 mm
- Steel (raw, zinc-plated), stainless steel, brass, etc.
The Intervis® self-tapping threaded insert is screwed directly into a smooth hole drilled beforehand. The intervis® cuts the thread in the part itself. It is ideal to be installed in medium-hard materials: light alloys, compressed wood or plastic materials.

From design to serial production of your parts
Co-Design and Development
1
In close collaboration with the engineers of the LGC design office, you will define the specifications, technical requirements and constraints of the project.
- Feasibility control using the FMEA tool, which is used to analyze failure modes, their effects and their criticality.
Prototyping and Testing
2
Once the concept is approved, the project team creates physical prototypes using a 3D machine and simulation software such as SolidWorks Premium, Spacerclaim.
- Manufacture of initial samples in medium series, and validation of production with PPAP according to the IATF 16949 standard.
Industrialization and Production
3
The serial transition is carried out according to the validated process according to the production control plan written by a multidisciplinary team.
- Development of detailed production processes according to the APQP quality process
Assessment and Improvement
4
After 3 to 6 months of series production, an evaluation based on the criteria required by the IATF 16949 standard verifies the conformity of the project at 100%.
- Collection and analysis of production data to identify trends and variations. 3PPM in 2023.

What is a specific and tailor-made Intervis® threaded insert?
A custom Intervis® threaded insert is a cylindrical fastener used to create strong and durable threads for a specific application.
The use of threaded inserts is possible in a wide variety of materials such as plastics, composites, and soft and medium-hard metals. These custom-made inserts are designed to meet specific needs according to the applications and specific technical requirements of each project.
Thanks to a customized design, custom threaded inserts offer a reliable and effective solution for reinforcing fasteners with threads in industrial applications that require high assembly strength.
They are used both as an initial fastener and for the repair of damaged threads.
Whether for the assembly of plastic parts in the automotive industry, the attachment of components in composite aircraft, or for unique applications in varied environments, Intervis® custom threaded inserts guarantee optimal tear resistance and exceptional mechanical properties.
What is the particularity of Intervis® specific and tailor-made threaded inserts?
Intervis® custom threaded inserts stand out for their ability to be adapted to the precise needs of your applications. Unlike standard threaded inserts, these inserts are manufactured according to exact specifications provided during co-design to meet specific technical requirements. This includes variations in size, material, shape, and specific characteristics like slits or coatings.
Custom threaded inserts are commonly used in soft materials like standard threaded inserts :
- The wood
- The plastic
- Composites
These inserts are found in a variety of demanding industrial applications such as:
- The automobile
- The fixing of electronic cards
- Attaching components to bikes, skis, and snowboards
- Plastics as an overmolded element
How is a custom Intervis® threaded insert made?
The manufacturing process for Intervis® custom threaded inserts is similar to that of standard threaded sockets, but with customized steps to meet unique specifications.
First step: the external thread of the raw material coil
This step, called rolling, consists in passing the tube between rollers to create the external thread of the insert by cold deformation.
Second step: cutting the raw material tube
The tube is cut to the desired length, with specific chamfer or finish options depending on the needs.
Step Three: Milling
A cutter cuts the part to create slots or other specific features required for the application.
Final step: tapping
The internal thread of the insert is made by a rotating tap which gives the insert its self-tapping functionality.
Then come new steps, such as surface treatments, and other machining processes depending on the technical nature of your request.
What are the advantages of a specific and tailor-made threaded insert?
Custom-made Intervis threaded inserts offer several distinct advantages:
- 97% improvement problem of wear of the taps
- 2.4x faster to install than other fillet repair systems
- 50% reduction in tooling costs (compared to a hot insert or utlarson)
- 32% increased pull-out resistance on comparable parts
