Hexagonal Blind Hole Nut

Product introduction

Hexagonal blind hole nut, also known as blind nut, is an exquisitely designed fastener. The outside is a standard hexagonal structure, which is easy to install and lock with general tools; the inside is a blind hole thread with one end closed. This design is its core highlight.

 

This product is mainly used in scenarios where it is necessary to hide the thread end, prevent media leakage, or improve safety and aesthetics. It can effectively isolate external dust and moisture from intruding into the system through the threads, while preventing sharp bolt ends from being exposed and causing scratches, significantly improving the safety level of the equipment. It is widely used in fields such as furniture, medical equipment, precision instruments, auto parts, and public facilities that require appearance and sealing. It is an ideal choice for achieving clean, safe, and reliable terminal connections.

 

Product Features

1. The end is closed, clean and leak-proof: The blind hole design is its most significant feature, and one end of the nut is completely closed. It can effectively prevent dust, moisture, gas and other media from intruding into the interior of the equipment through the threaded holes, keeping the interior clean, and also preventing internal lubricants or fluids from leaking.

2. Safe and beautiful, no risk of scratches: The closed-end design prevents the ends of the bolts from being exposed after assembly, eliminating sharp thread edges, effectively preventing the risk of scratches to operators and cables, and improving the safety and overall aesthetics of the product.

3. Reliable fastening, anti-loosening and anti-seismic: It adopts a hexagonal shape and can be installed using a standard wrench. It can provide powerful torque and achieve a solid mechanical connection. Combined with the design of the flange surface, it can further enhance the anti-loosening and anti-seismic performance and ensure the long-term reliability of the connection.

4. Thread protection and corrosion resistance: The blind hole structure can protect the internal threads from collision damage, corrosion and contamination during transportation, storage or non-use, ensuring that the threads are always in good condition and facilitating the smooth screwing of bolts.

5. Wide range of applications and increased value: Its safety, cleanliness and beauty make it popular in fields with high safety and appearance requirements such as furniture, medical equipment, precision instruments, automobile modifications, electronic products and public facilities, effectively improving the quality of end products.

 

Product application

1. Furniture and home furnishing industry: application scenarios: high-end assembled furniture, children's furniture, outdoor leisure furniture. Specific use: used for the installation of handrails, brackets, connecting rods, etc. Its blind hole design can hide the end of the bolt, making the appearance cleaner, and effectively prevents users from being scratched, especially for children's safety.

2. Medical equipment and fitness equipment: Application scenarios: Adjustment knobs and handles of hospital beds, wheelchairs, diagnostic equipment, and fitness equipment.

Specific use: The closed end cap can prevent dust and bacteria from invading the internal threads, facilitate cleaning and disinfection, and comply with the hygienic standards of medical equipment. At the same time, the risk of clothing or skin being caught is avoided.

3. Automobiles, transportation and public facilities: Application scenarios: automobile interior panels, passenger car interiors, subway handrails, park benches, guardrails. Specific use: Provides a smooth, edge-free surface to prevent accidental scratches in densely populated public spaces. At the same time, it can prevent rainwater and dirt from accumulating in the bolt holes and slow down corrosion.

4. Precision instruments and electronic equipment: Application scenarios: scientific instrument casings, measuring equipment, high-end audio, and communication cabinets. Specific use: It acts as a dust-proof and moisture-proof seal to protect internal precision components. The clean appearance also enhances the overall quality and value of the product.

5. Fluid pipelines and systems: Application scenarios: pipeline supports, valve fixing seats, and equipment bases that require unilateral blocking. Specific use: Under certain circumstances, its closed end can be used as a simple plug to prevent fluid or foreign matter from leaking or entering from the thread end, achieving a simple sealing function.

 

FAQ

Q: What is the main function of the "blind hole" design of hexagonal blind hole nuts?

A: The "blind hole" design mainly has three core functions: Safety protection: completely covers the end of the bolt, eliminates sharp edges, and prevents scratches on people and objects. Sealed and dust-proof: effectively prevents dust, moisture, and impurities from entering the interior of the device through the threaded holes, keeping the interior clean. Beautiful and neat: Provides a smooth, complete appearance and enhances the overall texture of the product.

 

Q: Will the blind hole design affect the screwing depth of the bolt?

A: Yes. This is a key point in usage. The screwing length of the bolt cannot exceed the effective depth of the blind hole, otherwise it will push against the closed end, making it impossible to tighten, and even damaging the threads inside the nut or causing the nut to deform. Always ensure that the selected bolt length is less than (blind hole depth + plate thickness).

 

Q: Does the hexagonal blind hole nut have an anti-loosening function?

A: The standard model does not have specific anti-loosening features. But if necessary, you can choose a hexagonal blind hole nut with a nylon insert to prevent loosening, or use it with a washer to enhance the anti-seismic and anti-loosening performance.

 

Q: Can it be used in pressure environments requiring high sealing?

A: Not recommended. Its blind hole design mainly provides static protection against dust and dripping, and is not designed to withstand pressure. In situations where pipes or containers need to withstand fluid pressure for sealing, special pipe joints, sealing nuts or flanges should be used.
