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. It is typically made from high-strength stainless steel wire and features a coiled design that restores or strengthens the original threads, ensuring that bolts, screws, or other fasteners can be securely fastened. Well-known brands of these inserts include Heli-Coil and Time-Sert.

• Thread Repair: When a threaded hole becomes stripped or damaged, a wire thread insert can be inserted to recreate the original threads, allowing the use of standard fasteners without the need to replace the entire part.
• Strengthening Threads: In softer materials, such as aluminum or plastics, a wire thread insert can provide additional support to the threads, improving their load-bearing capacity.
• Preventing Thread Damage: In high-stress applications, wire inserts help distribute loads more evenly, reducing the likelihood of thread stripping or loosening.
• Corrosion Resistance: Inserts made from corrosion-resistant materials like stainless steel or other alloys offer increased protection against rust and wear, especially in harsh environments.
• Cost-Effectiveness: Galvanizing is a relatively low-cost method compared to other corrosion-resistant treatments, such as using stainless steel or more complex coatings.
• Aesthetic Appeal: The surface of galvanized steel has a bright, silver-like appearance, which can be visually appealing and is often used in applications where appearance is important.

• Construction: Galvanized steel is used in structural components, roofing, pipes, and building materials.
• Transportation: It's found in bridges, guardrails, utility poles, and other infrastructure elements exposed to the elements.
• Appliances: Galvanized steel is used for the exterior parts of household appliances and automotive components.
• Agriculture and Water Management: It's used in greenhouses, irrigation pipes, and agricultural equipment that require long-term durability in outdoor environments.

• Aerospace: Wire thread inserts are widely used in the aviation and aerospace industries to repair or reinforce threads in critical components that require precision and reliability.
• Automotive: In the automotive sector, they are commonly employed to repair or strengthen threads in engine blocks, transmission housings, and other high-stress parts, particularly those made of softer metals like aluminum.
• Industrial Equipment: Wire thread inserts are often used in machinery and equipment to repair damaged threads, enabling the reuse of components without compromising safety or performance.
• Electronics: In precision electronics, wire inserts ensure that screws and bolts stay securely fastened, even in delicate or compact assemblies.

• Corrosion Resistance: The zinc coating forms a protective layer on the steel surface, which prevents direct contact with moisture, air, and chemicals, thereby preventing rust and corrosion.
• Weather Resistance: Galvanized steel performs well in outdoor environments, especially in harsh conditions like high humidity or coastal areas.
• Extended Service Life: Galvanized carbon steel is far more durable than uncoated steel, and its corrosion resistance can significantly increase its lifespan.
• Increased Mechanical Strength: The zinc layer adds hardness to the surface of the steel, providing additional wear resistance and mechanical strength.

201, 304, 316 are austenitic stainless steel, according to the performance of the non-magnetic, some of the performance of the weak magnetic because of the smelting of the composition of the segregation or improper heat treatment leads to the austenite in a small amount of martensite or ferrite. Austenitic stainless steel corrosion resistance comes from the formation of chromium oxide protective layer on the metal surface.
