Custom-made Intervis® threaded inserts
- 20 million specially slotted threaded inserts designed every 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, case-hardened zinc-plated), stainless steel, brass, etc.
The Intervis® self-tapping threaded insert is screwed directly into a pre-drilled smooth hole. Intervis® itself cuts the thread in the workpiece. It is ideal for use in medium-hard materials such as light alloys, compressed wood and plastics.

From design to mass production of your parts
Co-design and development
1
Working closely with LGC's design engineers, you will define the project's specifications, technical requirements and constraints.
- Feasibility checks using the FMEA tool, which is used to analyze failure modes, their effects and criticality.
Prototyping and Testing
2
Once the concept has been approved, the project team creates physical prototypes using a 3D machine and simulation software such as SolidWorks Premium and Spacerclaim.
- Production of initial samples in medium series, and validation of production with PPAPs in accordance with IATF 16949.
Industrialization and Production
3
The production process is validated according to the production control plan drawn up by a multi-disciplinary 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 assessment based on the criteria required by IATF 16949 verifies 100% project conformity.
- Collection and analysis of production data to identify trends and variations. 3PPM in 2023.

What is an Intervis® customized threaded insert?
An Intervis® custom threaded insert is a cylindrical fastener used to create strong, durable threads for a specific application.
Threaded inserts can be used in a wide variety of materials, including plastics, composites and soft and medium-hard metals. These made-to-measure inserts are designed to meet specific needs according to the particular applications and technical requirements of each project.
Thanks to their customized design, custom threaded inserts offer a reliable and effective solution for reinforcing fasteners with threads in industrial applications requiring high assembly strength.
They are used both as initial fasteners and for repairing damaged threads.
Whether for assembling plastic parts in the automotive industry, fastening components in composite aircraft, or for unique applications in a variety of environments, Intervis® custom threaded inserts guarantee optimum pull-out resistance and outstanding mechanical properties.
What's so special about Intervis® custom threaded inserts?
Intervis® custom threaded inserts are distinguished by their ability to be tailored to the precise needs of your applications. Unlike standard threaded inserts, these inserts are manufactured to exact specifications provided during co-design to meet particular technical requirements. This includes variations in size, material, shape and specific features such as slots or coatings.
Customized threaded inserts are commonly used in soft materials like standard threaded inserts :
- The wood
- Plastic
- Composites
These inserts can be found in a variety of demanding industrial applications such as :
- The automobile
- Fixing electronic boards
- Fastening components in bicycles, skis and snowboards
- Plastics as an overmolded component
How is a custom-made Intervis® threaded insert made?
The manufacturing process for Intervis® custom threaded inserts is similar to that of standard threaded bushes, but with customized steps to meet unique specifications.
First stage: external threading of the raw material coil
This stage, known as rolling, involves passing the tube between rollers to create the external thread of the insert by cold forming.
Second step: cutting the raw material tube
The tube is cut to the desired length, with the option of chamfers or specific finishes depending on requirements.
Third step: milling
A milling cutter cuts the part to create slots or other specific features required for the application.
Last step: tapping
The insert's internal thread is created by a rotating tap, giving the insert its self-tapping functionality.
This is followed by further steps, such as surface treatments, and other machining processes, depending on the technical nature of your request.
What are the advantages of a customized threaded insert?
Intervis custom threaded inserts offer several distinct advantages:
- 97% improvement in thread wear
- 2.4x faster to install than other net repair systems
- 50% reduction in tooling costs (compared with a hot-melt or utlarson insert)
- 32% more resistance to tearing than comparable parts
