2024 Top 10 Suppliers for Bolt Nut and Washer in China

Bolt nuts and washers are vital components in CNC machining that secure and fasten materials together.

Bolt nuts are metallic fastening devices that have undergone threading before being fit into a hole of the same size as the bolt nut.

Washers are components that enhance the control over nuts as they provide friction and tighten the bolt nuts in place.

There is a massive market for bolt nuts and washers worldwide. China is widely known as the pioneer of bolt nuts and manufacturers and contains some leading CNC equipment manufacturing companies.

Importance of Bolt Nuts

  • Bolt Nuts undergo a threading process that holds two or more components together, providing a sturdy connection. 
  • Bolt Nuts have many universal applications and are common components in machines. They are a vital part of CNC machining as they have simplified installation and uninstalling processes, which improves efficiency.
  • Bolt Nuts are very reliable fasteners as they have a robust defense mechanism against corrosion, which makes them last longer than other fasteners. 
  • Bolt Nuts are easy to produce as well. They do not require special heat or other conditioning treatments, which speeds up their manufacturing process.

Importance of Washers

  • Washers protect the joint surface from damage while tightening the nuts. They control the tension within the bolt using torque. This feature creates friction between the bolt and the surface and helps create a tight vacuum which leads to a strong connection.
  • Washers protect surfaces from damage due to the stress of the bolt head. Washers are made of a softer material than the bolt head and resist the pressure exertion of the head. This exerted pressure may result in permanent dents on the surface, which the washer prevents.
  • Washers prevent the loss of plastic deformations that may occur under the bolt head, in the threads, and joint faces. The use of washers increases the joint’s interfaces, reducing the bolt’s loss of tension. Using bolt nuts without protection can result in a loss of surface integrity and may cause the nut to loosen.
  • Washers absorb vibrations and damp these vibrations, which protect the nuts from the object from any damage. They offer protection from liquids by creating a waterproof seal from soft, waterproof materials. This feature makes them crucial elements in water and oil pipes.
