What Are Fasteners?

Fasteners are a type of mechanical parts that are used for fastening connections, which are widely used in many fields.

It is widely used in various industries, and can be seen in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and systems, etc.

Fasteners are the most widely used mechanical foundation parts.

It is characterized by a wide variety of specifications, different performance uses, and a very high degree of standardization, serialization and generalization.

Therefore, some people also refer to a type of fasteners with existing national standards as standard fasteners, or simply as standard parts.

What Are Custom Made Fasteners?

Custom made fasteners also called non-standard fasteners.

As the name implies, do not have standards, they are non-standard parts and require buyers to provide detailed drawings.

For example, DIN912, the Chinese name is hexagon socket head screw, which is the name of the product.

However, the most accurate way is to call the standard, because GB70 is also the same name, but there are many places where the two standards are inconsistent in size.

The most influential standards in the world are: German Standard (DIN), International Standard (ISO), Chinese National Standard (GB), American Standard (ANSI), and Japanese Standard (JIS).

What Materials Can Be Used For Custom Made Fasteners?

Custom made fasteners can be divided into many categories according to its production raw materials: Stainless steel customized fasteners, nickel alloy customized fasteners, titanium customized fasteners, aluminum customized fasteners, copper and brass customized fasteners, etc.

From below list, you can learn which materials can be used to its production.

Stainless SteelSS201, SS301, SS303, SS304, SS316L, SS416, SS2205, SS2507, SS904L etc
Nickel AlloyAlloy 400, K-500, 718, 625, 601, 600, 825, 800, 800H, 800HT, C22, C276, B, B2, B3, C4, C2000, G-35, 230, X750, 617, 925, GH2132, GH2747, GH3044, GH3030, GH3128, GH4033, GH4145, GH4169, GH4199, etc

AluminumAL6061, AL6063, AL6082, AL7075, AL5052, A380, etc
TitaniumGr1, Gr2, Gr5, etc

What Are Custom Made Fasteners Surface Treatment?

Custom made fasteners surface treatment is one of the major part in whole production.

Different surface finish will be used for different applications.

Customers can choose the corresponding surface finish according to their own usage.

With methods including anodizing, passivation, brushing, polishing, blackened, plating, painting, powder coating, heat treatment, surface phosphating, hot dip galvanizing, surface treatment dacromet, etc.

The Difference Between Custom Stainless Steel Fasteners And Non-standard Special Nickel Alloy Fasteners

1.The definitions are different:

Non-standard nickel alloy fasteners are special kind of stainless steel parts, which are high-alloy stainless steel fasteners containing high nickel, high chromium and high molybdenum.

Custom stainless steel fasteners are the abbreviation of stainless steel parts, and the types of them that are resistant to weak corrosive media such as air, steam, and water, or have rust properties.

2.Different Performance:

Non-standard nickel alloy fasteners have very good corrosion resistance.

Under the conditions of seawater, gas, crevices, and low-speed scouring, they have good pitting corrosion resistance and good stress corrosion resistance.

Custom stainless steel fasteners are substitute for Ni-based alloys and titanium alloys fasteners.

Types of Industry Where Custom Made Stainless Steel Bolts Are Used

The custom made stainless steel bolts are mainly used in the following industries:

  • Heat Exchanger Equipment
  • Chemical Fertilizer Industry
  • Chemical and Petrochemical Industry
  • Power Generation and Environmental Technologies
  • Oil and Natural Gas LNG Industry
  • Mechanical and Plant Engineering
  • Construction and Ship Building
  • Automotive Industry
  • Nuclear Power
  • Instrumentation Tubing
  • Pulp and Paper Make Industries
  • Chemical Fiber
  • Food processing industry Sanitary Tubes
  • Environmental Protection Industry
  • Aerospace And Defense Industry

Types of Industry Where Custom Made Special Alloy Bolts Are Used

Custom made special alloy bolts are used in many fields, such as:

  1. Ocean: marine structures in the marine environment, seawater desalination, seawater aquaculture, seawater heat exchange, etc.
  2. Environmental protection: flue gas desulfurization device for thermal power generation, wastewater treatment, etc.
  3. Energy: atomic power generation, comprehensive utilization of coal, ocean tide power generation, etc.
  4. Petrochemical: oil refining, chemical and chemical equipment, etc.
  5. Food Industry: salt making, soy sauce brewing, etc.

What Are Custom U Bolts Used For?

There are many types of bolts. Cylindrical bolts are common seen, but there are also many special-shaped bolts, such as custom U bolts.

U bolts are U-bolts in shape.

Both ends of the thread can be combined with nuts. They are mainly used for fixing pipes such as water pipes or automobile leaf springs.

The material properties, density, bending strength, impact toughness, compressive strength, elastic modulus, tensile strength, temperature resistance and color of the U-bolts are determined according to the use environment.

Custom U bolts are generally used in trucks to stabilize the chassis and frame of the car.

Custom U bolts have a wide range of uses, such as building installation, mechanical fittings connection, vehicles, ships, bridges, tunnels, railways, etc.

Custom U bolts are often seen in industrial and mining enterprises.

In addition, custom U bolts are one of the more widely used types of bolts in the minds of many of engineers.

What Are The Applications That Custom Made Brass Bolts Can Be Used?

Custom made brass bolts are defined as customized bolts made of brass (HPb63, HPb62, HPb61, HPb59, H59, H68, H80, H90, etc).

Custom made brass bolts have the advantages of not easy to rust, anti-corrosion, easy to conduct heat and strong electrical conductivity.

Custom made brass bolts are widely used in electronics, communications, HVDC systems, electrical appliances and other industries.
