Applications of Wire Thread Inserts
Aerospace
Used in aircraft engines, airframes, and avionics systems to provide durable and lightweight threaded connections that withstand vibration and thermal stress.
Automotive
Applied in engine blocks, gearboxes, and chassis components for reliable thread performance in high-temperature and high-vibration environments.
Electronics and Consumer Devices
Installed in lightweight enclosures and housings to prevent thread stripping in plastic or soft metal components.
Industrial Machinery
Ensures strong and reusable threads in castings, aluminum components, and equipment requiring frequent assembly/disassembly.
Marine and Shipbuilding
Utilized in high-corrosion environments for stainless steel thread reinforcement in structural and equipment installations.
Medical Devices
Supports reliable fastening in surgical equipment and diagnostic devices where hygiene and precision are essential.

FAQs About Wire Threaded Inserts
1. What Are Wire Threaded Inserts?
Wire threaded inserts are helical coils made from stainless steel, installed into pre-tapped holes to create a high-strength, wear-resistant internal thread. They are used to enhance thread performance in soft materials or to repair damaged threads.
2. What Materials Are Wire Threaded Inserts Suitable For?
Wire inserts are especially suitable for soft or low-strength base materials such as:
Aluminum and its alloys
Magnesium alloys
Plastics
Wood (certain structures)
Cast iron or light alloy castings
They greatly improve thread strength and wear resistance in these materials.
3. What Are the Main Applications of Wire Inserts?
Reinforce threads in soft base materials
Repair stripped or damaged threads
Convert between metric and imperial thread systems
Improve resistance to loosening under vibration or frequent disassembly
Ensure long-term durability of thread connections
4. Are Wire Threaded Inserts Reusable?
The inserts themselves can be reused, but over-tightening the screw can damage the internal coil. If an insert loosens or fails, it must be replaced with a new one.
5. How Do I Choose the Correct Insert Size?
You should consider:
The external diameter and pitch of the mating screw
The diameter and depth of the tapped hole
Required load-bearing strength
Whether the purpose is thread repair, reinforcement, or conversion
Refer to standard sizing charts (e.g., ISO, UNC, UNF) for selection.
6. What Tools Are Needed for Installation?
Installation usually requires:
Insertion tools (manual or powered handles)
Drill bit (to prepare the hole)
Tap (to cut the threaded hole)
Tang break-off tool (for inserts with tangs)
Brands like Recoil and Heli-Coil offer complete installation kits.
7. What Types of Wire Inserts Are Available?
Common types include:
Tanged Inserts: Require tang removal after installation
Tangless Inserts: Used in applications where tang remnants are unacceptable
Self-locking Inserts: Designed for vibration resistance
Extended or fine-thread custom inserts
8. Are Wire Inserts Corrosion Resistant?
Most are made from stainless steel (304 or 316), offering good corrosion resistance. For marine or chemical environments, you can choose nickel-plated or 316L stainless steel for enhanced durability.
9. Can Wire Threaded Inserts Be Customized?
Yes. Rivetfix provides full customization options for material, size, structure (self-locking, knurled, etc.), and surface finish (e.g., phosphate, nickel-plated, color zinc) to suit specific project requirements.
10. What Is the Typical Service Life of Wire Inserts?
When properly installed and used, wire inserts can last through thousands of installation/removal cycles—far exceeding the durability of directly tapped threads in soft materials. Their lifespan depends on usage conditions and maintenance.
