Wire Thread Insert

Threaded wire inserts are precision-embedded fasteners designed to repair, reinforce, or enhance thread strength. They are made from high-strength, high-elasticity cold-rolled stainless steel wire, accurately coiled into a diamond-shaped cross-section. When installed into pre-tapped holes in the base material, they form durable, wear-resistant standard internal threads.

These inserts are mainly used in low-strength materials such as aluminum, magnesium alloys, plastics, and wood, or for repairing damaged threads in cast iron and steel components. They significantly improve the load-bearing capacity, fatigue resistance, and wear resistance of threaded connections while ensuring thread standardization and interchangeability.

Applications
Threaded wire inserts are widely applied in industries requiring high-precision and highly reliable threaded connections, including:
Automotive: Engine components, chassis parts, and structural assemblies requiring strong, durable threads.
Aerospace: Lightweight alloy parts that need high-strength and fatigue-resistant threads.
Marine: Corrosion-resistant threaded connections for shipbuilding and marine equipment.
Precision Machinery: Critical components in machines and molds requiring long-lasting threaded connections.
Electronics: Plastic or metal housings in electronic devices where secure thread reliability is essential.
