M5 M8 Carbon steel Galvanized eye Nut Grade8.8 Class 8.8 Customized Zinc Plating

M5 M8 Carbon steel Galvanized eye Nut Grade8.8 Class 8.8 Customized Zinc Plating

Product Description:

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.

Key Functions:

1. 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.

2. 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.

3. Preventing Thread Damage: In high-stress applications, wire inserts help distribute loads more evenly, reducing the likelihood of thread stripping or loosening.

4. 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.

Applications:

• 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.

In conclusion, wire thread inserts are a versatile and effective solution for thread repair and reinforcement in a wide range of industries, offering cost-effective and durable results for maintaining threaded connections.

Galvanized carbon steel refers to carbon steel that has been coated with a layer of zinc through processes such as hot-dip galvanizing or electroplating. The primary purpose of galvanizing is to enhance the corrosion resistance of carbon steel and extend its service life. The benefits and functions of galvanized carbon steel include:

1. 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. Even if the zinc layer is damaged, zinc protects the exposed steel through sacrificial anode action, where zinc corrodes preferentially over steel.

2. Weather Resistance

• Galvanized steel performs well in outdoor environments, especially in harsh conditions like high humidity or coastal areas. It is resistant to various weather conditions, making it ideal for applications such as building exteriors, bridges, and transportation infrastructure.

3. Extended Service Life

• Galvanized carbon steel is far more durable than uncoated steel, and its corrosion resistance can significantly increase its lifespan, often by several times, reducing maintenance costs and the need for frequent replacements.

4. Increased Mechanical Strength

• The zinc layer adds hardness to the surface of the steel, providing additional wear resistance and mechanical strength. This is beneficial for applications that require durable, long-lasting materials.

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. When the material temperature is heated to 450 degrees -900 degrees, the structure changes, will form chromium carbide along the edge of the crystal and can not form a protective layer of chromium oxide, thus reducing the corrosion resistance, this is also known as ‘intergranular corrosion’. As a result, there are 304L and 316L, the two due to the low carbon content also reduces the intergranular corrosion. In particular, the higher susceptibility to intergranular corrosion does not mean that non-low carbon content is more susceptible to corrosion, in a highly chlorinated environment, this susceptibility is also higher.

304 stainless steel
304 is a general-purpose stainless steel that is widely used to make equipment and machine parts that require good all-round performance (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.

A2 stainless steel and A4 stainless steel, A2 is a class of 304 stainless steel, A4 is a class of 316 stainless steel, the main difference between the two is here, some of the fastener industry will be 302HQ and 304 referred to as: A2, 316 and 316L (C content of carbon C is less than 03% of the stainless steel, you can increase the ‘L’ logo) called A4.

What is the difference between a270 and a470 stainless steel bolts Nuts are usually used in conjunction with bolts. Hexagonal nuts are more widely used.C-grade hexagonal nuts are used in steel structures, machinery and equipment with rough surfaces and low requirements for precision.A-grade and B-grade hexagonal nuts are mainly used in machinery and equipment with smooth surfaces and high requirements for precision.
