Yellow purple Carbon steel Wire Thread Insert Customized Anodizing finishing M6 M8

A wire thread insert (also known as a helical thread insert or coil insert) is a mechanical component used to repair or reinforce damaged or worn threaded holes. Made from high-strength carbon steel wire with customized anodizing finishing, these inserts restore or strengthen original threads, ensuring secure fastening of bolts and screws.

• Thread Repair: Recreates original threads in stripped or damaged holes, eliminating the need to replace entire parts.
• Thread Strengthening: Provides additional support in softer materials like aluminum or plastics, improving load-bearing capacity.
• Damage Prevention: Distributes loads evenly in high-stress applications, reducing thread stripping or loosening.
• Corrosion Resistance: Anodized finishing offers increased protection against rust and wear in harsh environments.
• Cost-Effectiveness: Provides durable thread solutions at lower cost compared to part replacement.

• Aerospace: Critical component thread repair and reinforcement requiring precision and reliability.
• Automotive: Engine blocks, transmission housings, and other high-stress parts in softer metals.
• Industrial Equipment: Machinery thread repair enabling component reuse without compromising safety.
• Electronics: Secure fastening in precision and compact assemblies.

• Enhanced corrosion resistance against moisture, salt, and harsh environments
• Increased surface hardness and wear resistance
• Customizable colored finishes for decorative applications
• Excellent electrical insulation properties
• Environmentally friendly process without harmful chemicals

Austenitic stainless steels like 201, 304, and 316 are generally non-magnetic, with weak magnetic properties sometimes occurring due to composition segregation or heat treatment. The corrosion resistance comes from chromium oxide protective layers. At temperatures between 450°C-900°C, chromium carbide formation can reduce corrosion resistance (intergranular corrosion), which is why low-carbon variants (304L, 316L) are available for high-chloride environments.
