Boltnuts, also known as draw caps, are used in the fastening field for various metal sheet materials, pipes, and other manufacturing industries. They are widely applied in the assembly of automotive, aviation, railway, refrigeration, elevator, switchgear, instruments, furniture, and decorative products. Developed to address the defects of metal thin plate and thin pipe welding nuts, which are prone to melting, base material deformation during welding, and easy thread stripping, these nuts do not require internal threading, welding, or riveting. They offer high efficiency and ease of use. Boltnuts effectively solve issues with air conditioner casings and can effectively eliminate problems like cold joints.

Boltnut applications in air conditioning:

Boltnuts effectively address the issue of "yellow water" on air conditioner casings over time, and can effectively prevent issues such as cold welding.

2. Rivet nuts replace flanged threads, allowing for a 20% material reduction and energy savings.

3. Solve the issue of loose connections in self-tapping screws, enhancing reliability. This can reduce noise caused by loose connections and make the product more reliable and sturdy, while also being easy to repair.

4. Enhance production efficiency, reduce labor force, and lower labor costs. (Due to the use of stamping and riveting techniques for the rivet nuts, which allows for a single-welding process to be completed in one go, not only is the efficiency high, but it also reduces the amount of labor required.)

5. Reduce factory floor usage.
