Thread Inserts for Sale
A wire thread insert is a helical coil made from high-strength stainless steel wire, typically used to be installed into a pre-tapped hole to create a standard-sized, high-strength internal thread. This design significantly enhances the thread strength of the parent material, especially in softer materials like aluminum or magnesium, effectively preventing thread stripping, wear, and pull-out. Once installed, the wire thread insert provides a durable, corrosion-resistant threaded interface suitable for high-frequency assembly and disassembly or high-strength applications. Wire thread inserts are also known as helical inserts or screw thread inserts, and are often referred to by brand names such as Recoils or Helicoils.
Thread Inserts Manufacturer in China
Wire thread inserts are widely used in both industrial and repair applications, with their main functions including:
Enhancing Thread Strength: They provide stronger and more durable internal threads for materials with low strength, such as aluminum or aluminum-magnesium alloys, preventing thread stripping or pull-out.
Repairing Damaged Threads: For worn, corroded, or damaged internal threads, wire thread inserts offer a cost-effective solution to restore the original thread function.
Thread Conversion: They enable conversions between metric and imperial (inch-based) threads, accommodating different bolt standard requirements.
Improving Fatigue and Vibration Resistance: Due to their elasticity, wire thread inserts can absorb vibration and distribute loads evenly across each coil, thereby increasing the fatigue resistance and stability of the threaded connection.
Wire thread inserts are most commonly used to reinforce threads in OEM castings and machined parts made from lightweight but inherently weaker materials—aluminum being the most prevalent.

1. Tanged Coil Thread Inserts
Description:
Tanged inserts have a small notch or “tang” at the bottom of the coil. This tang is used to drive the insert into the threaded hole using an installation tool.
Key Features:
Standard and widely used type
Tang is broken off after installation using a tang break-off tool
Suitable for most general industrial applications
Available in free-running and screw-locking styles
2. Tangless Coil Thread Inserts
Description:
Tangless inserts do not have a tang at the bottom. Instead, they have notched ends on both sides, allowing for bidirectional installation and removal.
Key Features:
No tang to remove, simplifying installation and eliminating FOD (Foreign Object Debris) risk
Easier removal and repositioning
Ideal for cleanroom, aerospace, and medical device applications
Available in 2-notch (for manual install) and 4-notch (for automated install) versions

Custom Riveting Solutions for Various Industries
Custom Thread Inserts for Automotive
Wire thread inserts are used in engine blocks, transmission housings, and suspension systems to provide strong, wear-resistant threads in lightweight materials like aluminum. They help prevent thread stripping and ensure long-term reliability under vibration and thermal cycling.
Custom Thread Inserts for Industrial Electronics
In industrial control systems and heavy-duty electronic enclosures, wire inserts reinforce threaded connections that undergo frequent maintenance or mechanical stress, ensuring consistent fastening and electrical integrity.
Custom Thread Inserts for Consumer Electronics
Devices like laptops, smartphones, and home appliances often use wire thread inserts in plastic or soft metal housings to improve thread durability, especially where repeated assembly and disassembly are required.
Custom Thread Inserts for Aerospace – Avionics, Engines
Aerospace applications demand lightweight yet high-strength fastenings. Wire thread inserts are used in avionics systems, turbine engines, and aircraft structures to withstand high vibration, temperature fluctuations, and repeated maintenance cycles.
Custom Thread Inserts for Shipbuilding
In marine environments, wire thread inserts provide corrosion-resistant, secure threads in engines, hulls, and electronic components, even in harsh, high-moisture conditions.
Custom Thread Inserts for Power Generation
From wind turbines to gas turbines and nuclear power facilities, wire thread inserts are used to maintain secure, long-lasting threaded joints in equipment exposed to heat, vibration, and mechanical load.
