Internal And External Tooth Connectors With Anti-Loosening Glue

Product introduction

The internal and external tooth connector with glue to prevent loosening (usually refers to screws, bolts or studs coated with microcapsule pre-glued) is an advanced mechanical anti-loosening fastener. It has a special "nylon patch" or chemical adhesive pre-coated on the threads of the standard part. When the connector is screwed in and tightened, this layer of pre-coated glue will be squeezed and sheared, filling the thread gap and generating strong friction and locking force, thereby effectively resisting loosening caused by vibration, impact and thermal cycles. This product integrates thread locking and connection, eliminating the need for additional steps of using locking gaskets or liquid thread locking agents. It is easy to install and has high reliability. It is widely used in fields such as automobiles, aerospace, high-end equipment manufacturing and precision electronics that require extremely high anti-loosening reliability. It is an ideal solution to solve the problem of screw loosening in vibration environments.

Product Features

1. Excellent anti-loosening and anti-seismic performance: The core advantage lies in its strong anti-vibration and anti-impact capabilities. The pre-coated anti-loosening glue generates continuous friction and locking force after thread engagement, which can effectively cope with long-term vibration and dynamic loads and prevent the connecting parts from loosening on their own.

2. Reliable sealing and corrosion resistance: The cured adhesive layer can effectively fill the tiny gaps between threads, form a sealing barrier, prevent the leakage of gas and liquid, and block the intrusion of moisture and corrosive media, protect the thread base, and extend the service life.

3. Easy installation and high consistency: The product has been pre-coated with glue before leaving the factory. The installation process is the same as that of ordinary fasteners. There is no need to apply glue on site, saving time and effort. At the same time, it avoids unevenness, omissions or contamination problems that may be caused by manual glue application, ensuring that every connection has a stable and consistent anti-loosening effect.

4. Repeatable disassembly and reuse: Most models (especially the nylon type) allow a limited number of repeated disassembly and installation (usually 1-3 times are recommended), and can still maintain a certain anti-loosening ability after re-tightening, which facilitates on-site maintenance and inspection of the equipment.

5. Wide applicability: It can be used with standard internal threads or external threads of different materials, and has strong versatility. A variety of performance grades and adhesive types (e.g. nylon-based, chemical anaerobic adhesives) are available to accommodate different strength, temperature and environmental requirements.

Product application

1. Automobile manufacturing and transportation: widely used in bolt connections of key parts such as engines, gearboxes, chassis suspensions, wheels, and braking systems. Effectively deal with continuous vibration and impact during vehicle driving to ensure driving safety.

2. Aerospace and high-end equipment: used in high-precision equipment such as aircraft structural parts, spacecraft, drones and robots. Its extreme requirements for reliability and weight reduction make this highly efficient anti-loosening solution the first choice.

3. Industrial machinery and heavy equipment: commonly used in engineering machinery, vibrating screens, stamping equipment, wind turbines and large transmission systems, etc. It can effectively resist the strong vibration and alternating loads generated during the operation of heavy equipment, and prevent failures caused by loose bolts.

4. Precision electronics and electrical appliances: used in servers, communication base stations, high-end home appliances and other products to prevent screw loosening caused by micro-vibration and ensure the stability of electrical connections and long-term reliability of products.

5. Energy and chemical equipment: It has important applications in petrochemical, pipeline flanges, pump valves and other systems with pressure pulses and temperature cycles. Its dual functions of anti-loosening and sealing can effectively prevent leaks.

FAQ

Q: What is the anti-loosening principle of this anti-loosening connector?

A: The core principle is the combined effect of physics and chemistry. The glue layer pre-coated on the threads is squeezed and sheared during installation and tightening, resulting in huge friction. At the same time, chemical anaerobic adhesives will solidify in the anoxic environment of thread engagement to form a hard plastic layer, which together produce a strong mechanical locking force and effectively resist vibration and loosening.

Q: Can this adhesive product be reused?

A: This depends on the type of pre-coated glue: Nylon type (commonly known as red or purple patch): usually allows 1 to 3 reuses, after which the anti-loosening effect will decrease. Anaerobic adhesive type (commonly green): Once completely cured, the anti-loosening effect is basically lost after disassembly, and reuse is not recommended. If repeated disassembly is required, choose nylon type or reapply liquid locking agent after each disassembly.
