Non-metallic Insert Hexagon Lock Nut

The non-metallic insert hexagon lock nut is a common type of nut with anti-loosening function. The following is an introduction to the structural features, performance advantages, and application fields of the non-metallic insert hexagon lock nut:

Structural Features of the Non-metallic Insert Hexagon Lock Nut

Hexagonal Shape: It is similar in appearance to an ordinary hexagon nut, with six corners, which makes it convenient to operate with tools such as wrenches. It can provide a good surface for applying torque, ensuring even force during the fastening process and guaranteeing a reliable connection.

Non-metallic Insert: This is a key structure of the nut. Non-metallic materials such as nylon and plastic are usually used and embedded at one end of the nut. The inner diameter of the insert is slightly smaller than the pitch diameter of the nut thread. When the bolt is screwed in, the insert is extruded and deformed to fill the gap of the thread fit.

Performance Advantages of the Non-metallic Insert Hexagon Lock Nut

Good Anti-loosening Performance: When the bolt is screwed in, the non-metallic locking ring such as nylon is damaged and fills the thread gap. It has a completely extruded contact with the thread. The extruded nylon generates a large resilience force on the bolt, increasing the friction and effectively preventing the nut from loosening due to reasons such as vibration and impact. Especially, its anti-loosening performance is outstanding under small pre-tightening force and small amplitude.

Corrosion Resistance: The non-metallic insert and the stainless steel and other materials used for part of the nut body have good corrosion resistance. They can maintain good performance in harsh environments such as humidity and the presence of corrosive gases, thus extending the service life.

Good Insulation: The non-metallic insert has excellent electrical insulation properties. When it is used in some electrical equipment or occasions with insulation requirements, it can prevent current from passing through the nut, thus avoiding short circuits or other electrical failures.

Protecting the Connected Parts: The non-metallic insert plays a buffering role in the nut. It can effectively absorb the impact force and vibration generated during the operation process, protect the connected parts from damage, reduce the damage to the surface of the connected parts, and maintain the stability of the equipment operation.

Application Fields of the Non-metallic Insert Hexagon Lock Nut

Automotive Industry: It is used for the connection of components in parts such as automotive engines and chassis. It can withstand vibration and impact during the vehicle's running process, ensure the reliability of the connection, and prevent component damage caused by nut loosening.

Mechanical Manufacturing: It is widely applied to the assembly of various mechanical equipment, such as machine tools and reducers, etc. It ensures that the fasteners will not loosen due to vibration during the long-term operation of the equipment, and guarantees the normal operation of the equipment.

Electronic Equipment: It is suitable for the assembly of the casings of electronic equipment, the fixing of circuit boards, etc. Its insulation and anti-loosening performance can meet the requirements of electronic equipment for safety and stability.

Aerospace: In the aerospace field, the requirements for fasteners are extremely high. The non-metallic insert hexagon lock nut can provide reliable fastening force. At the same time, its characteristics such as light weight and corrosion resistance also meet the requirements of aerospace components, ensuring the safety of aircraft during high-speed flight and in complex environments.
