Round Head Square Step Blind Hole Nut

Product introduction

The round head square step blind hole nut is a professional fastener with well-structured design. Its naming intuitively reflects the core morphological characteristics: the head is a rounded arc surface, which can provide a smooth appearance transition and a good feel after installation; the body is a regular square columnar shape. This design can effectively prevent rotation during use when pre-embedded or press-in installation, ensuring fastening reliability. There is an obvious circular step in the middle of the product. This structure not only enhances the axial load-bearing strength of the part, but also accurately controls the installation depth, playing a positioning and reinforcing role. The threaded blind hole design means that the thread is not transparent to the top, which can prevent the front thread from being damaged during assembly. It can also seal the end of the tubular part to isolate dust and moisture, and improve the overall aesthetics. This nut is widely used in scenarios that require installation appearance, anti-rotation performance and sealing. It is an indispensable connecting element in the sheet metal industry, chassis cabinets, precision equipment and various decorative structures.

 

Product features

1. Reliable anti-rotation design. Its square columnar body can closely match the square hole of the mounting base, structurally completely preventing the nut from rotating during tightening or use, ensuring a long-term stable connection.

2. Excellent sealing and protection performance: The blind hole design makes the threads impermeable, which can effectively isolate dust, moisture and foreign matter from entering the threaded holes, protect the threads and improve the sealing and cleanliness of the connection points.

3. Precise installation positioning: The middle step structure can be used as a precise installation limit to ensure the same depth of each press, which facilitates automated production and quality control, and also enhances the axial load-bearing capacity of the nut.

4. Beautiful and sleek appearance: The round head design has a smooth transition and no sharp corners after installation. It not only provides a smooth and beautiful finished product appearance, but also improves the hand feel and safety of equipment operation.

5. Convenient assembly process The product is specially designed for pre-embedding or riveting processes. It can be installed before sheet metal parts are sprayed or assembled, simplifying subsequent assembly processes and significantly improving overall production efficiency.

 

Product application

1. Sheet metal structure and chassis cabinet This is its most typical application scenario. It is firmly embedded in the square pre-punched hole of the sheet metal part through riveting or pre-embedding. Its anti-rotation feature ensures that the screw hole position is always stable under frequent plugging and unplugging or vibration environments. It is widely used in the assembly of server cabinets, network equipment, industrial control boxes and various electrical appliance casings.

 

2. Precision instruments and high-end equipment In optical instruments, testing equipment, medical equipment and high-end home appliances, the aesthetics of the sleek head and the dust-proof sealing of the blind hole design are crucial. It can effectively prevent internal precision components from being contaminated and improve the overall texture and safety of product appearance.

 

3. Transportation tools: It is used in automobile interior parts, motorcycle parts, interior panels of rail transit vehicles, and box structures of outdoor vehicles (such as RVs and engineering vehicles). Its anti-vibration and anti-loosening performance and smooth appearance can meet the strict requirements of transportation for safety, durability and ergonomics.

 

4. Public facilities and outdoor equipment: Commonly found in outdoor communication base stations, power facilities, public seats, exhibition stands and sports equipment. Its solid structure can withstand complex environments, and the blind hole design can effectively resist the intrusion of rain, snow, and corrosive media, extending the service life of the equipment outdoors.

 

5. Furniture and decorative industry In modern metal furniture, display racks, lamps and architectural decoration components, this nut can achieve concealed and firm connections. After installation, the surface is flat and smooth, which can not only meet the load-bearing requirements, but also maintain a simple and smooth visual aesthetic, achieving the unity of function and design.

 

FAQ

Q: How to install this nut?

A: Mainly using pressure riveting process. Use special riveting equipment to press the square cylinder of the nut into the corresponding pre-punched square hole. The steps will be stuck on the board to provide positioning and limiting. Also suitable for mold pre-embedding.

 

Q: What are the main differences compared with ordinary welding nuts or blind rivet nuts?

A: The main difference lies in its anti-rotation and craftsmanship. The square structure provides the best anti-rotation protection; the riveting installation does not require welding, does not produce thermal deformation or welding slag, and avoids the space requirements on the back of the rivet nut, which is highly efficient and beautiful on the front.

 

Q: In addition to being beautiful, does the round head design have any other functions?

A: Yes. The round head can provide a smooth transition, eliminate sharp edges, improve safety in use (anti-scratch), and provide a better tactile experience in certain handheld or frequently touched areas.
