‍
Strengthen the mechanical resistance of your tapped holes and secure your assemblies in soft materials with our complete range of wire thread inserts, threaded inserts, and installation tools.

‍All our wire thread inserts are available in 

‍

  • A wide selection of thread diameters, allowing for use in a variety of thread repair applications.
  • Different thread types, such as metric threads with standard and fine pitches, as well as UNC, UNF, UNEF, and UNS threads.
  • Several materials to reinforce tapped holes, including stainless steel and bronze.

‍

Helicoil wire thread inserts are available in several thread types (metric, UNC, UNF, BSF), which you can find in various kit formats.

‍

What is a thread insert?

‍

A thread insert, also known as a helicoil, is an essential device for professionals. It is used to repair or reinforce damaged or worn threads in materials such as metal or plastic. It directly improves the strength of the tapped hole and your assembly by compressing perfectly when installed into the receiving threads of the tapped part.

A thread insert allows for the creation of stronger threads in new materials. This tool is highly useful in mechanics, the automotive industry, aeronautics, and many other fields requiring the assembly of mechanical parts.

The helicoil thread insert is a valuable device available in 304 stainless steel; this spring-shaped threaded insert is placed into a pre-tapped hole, thereby forming an internal thread.

With an outer diameter larger than that of the original hole, it effectively reinforces the thread. Once in place, the thread insert provides a new, wear-resistant thread capable of accommodating a bolt or screw.

They are most often used in materials with low shear strength, such as aluminum or aluminum-magnesium alloys.

‍

Why integrate our thread inserts into your mechanical assemblies?

‍

Using a Helicoil-type thread insert is not limited to repair. It is an engineering solution that optimizes bolted connections in materials with low shear strength (aluminum, aluminum-magnesium alloys, sheet metal, technical plastics):

‍

  • Optimal stress distribution: The flexibility of the thread insert compensates for pitch and flank angle errors, distributing the clamping load across all engaged threads.
  • Increased mechanical strength: Made from high-tensile A2 stainless steel (AISI 304) (up to 1,400 N/mm²), our inserts prevent thread stripping.
  • Thermal and corrosion protection: Excellent resistance to aggressive fluids, corrosion, and extreme temperature fluctuations.
  • Interchangeability and compliance with standards: Our products meet major industrial and international standards: DIN 8140, DIN 65536, LN 9590, LN 9499 and NASM 21209.

The Gardette wire thread insert range: from standard components to complete kits

To meet the needs of both production lines and emergency on-site repairs, our catalog covers all market standards:

‍

Types of wire thread inserts

‍

  • Standard (Free-Running) thread inserts: Ensure free rotation of the screw while reinforcing the receiving thread.
  • Screw-Locking thread inserts: Feature one or more polygonal coils that exert radial pressure on the screw to prevent loosening under heavy vibration.

‍

Variety of threads and materials

‍

  • Metric pitch: Coarse and fine pitch.
  • American and British threads: UNC, UNF, UNEF, UNS, BSF.
  • Available materials: AISI 304 / AISI 316 stainless steel (A4 for marine and chemical environments), phosphor bronze.
  • Packaging: Retail sales, industrial refills for medium and large production runs, or complete repair kits by diameter (including drill bit, STI tap, installation tool, and tang break-off tool).

‍

The Gardette commitment: responsiveness and local stock

‍

As a specialist in assembly and mechanical parts, the Groupe Gardette relies on a responsive logistics platform and over 25,000 stocked items in Villefranche-sur-Saône.

Whether you are looking to validate an integration plan in the design office or need urgent troubleshooting on an assembly line, our technical teams will assist you in selecting the diameters, thread engagement depths, and installation tools best suited to your production rates.
