Non-Standard Red Copper Nuts

Product introduction

The copper flat head nut (total length 103mm, thread depth 17mm, 1/4-28 thread) is a non-standard fastener specially designed for special working conditions. Made of high-purity red copper, it has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is especially suitable for sensitive environments such as electricity, explosion-proof, vacuum and anti-magnetic interference. The nut adopts a flat head design, which can achieve installation flush with the mounting surface without protrusions. The effective thread depth of 17mm ensures sufficient screwing length. Together with the 1/4-28UNF fine thread, it can provide more reliable connection strength, excellent anti-loosening, shock resistance and sealing performance. The total length design of 103mm enables it to have both connection and extension functions. This product is widely used in fields such as electrical equipment, semiconductor manufacturing, scientific research instruments and pipeline systems. It is an ideal choice to solve the special installation requirements of conductive connections, anti-corrosion and non-magnetic environments.

Material: copper

Surface treatment: clean color

 

Product Features

1. Excellent material properties: Made of high-purity copper, it has excellent electrical conductivity, thermal conductivity, corrosion resistance and non-magnetic properties. It is an ideal choice for sensitive environments such as electricity, electronics, vacuum and explosion-proof.

 

2. Unique flat head and long handle design: Flat head structure: It can realize installation flush with the installation surface without protrusions, with a neat appearance and avoid interference. Extra long overall length (103mm): Its long handle structure has both connection and extension functions, making it suitable for deep holes, mezzanines, or special assembly scenarios that need to span a certain distance.

 

3. Reliable threaded connection: 17mm effective thread depth: provides a screwing length that far exceeds that of standard nuts, ensuring extremely high connection strength, excellent anti-loosening and shock resistance, and sealing performance. 1/4-28UNF fine thread: The fine thread design makes the connection tighter, the adjustment more precise, and the self-locking performance better.

 

4. Wide range of professional applicability: Designed specifically to meet the demanding requirements of special industries, while ensuring mechanical performance, it perfectly solves the comprehensive needs for conductivity, rust prevention, non-magnetic and chemical corrosion resistance.

 

Product application

1. High-precision vacuum chamber and semiconductor equipment: Its non-magnetic and corrosion-resistant characteristics avoid contamination of sensitive environments. The flat head design ensures that the inner wall of the chamber is smooth and free of protrusions. The ultra-long handle facilitates cross-layer or deep hole connections in complex cavity structures.

 

2. Power electrical and bus connection system: Excellent conductivity makes it an ideal choice for electrical bus connection. The long thread depth provides strong bite force to ensure stable and safe connection when large current passes through, effectively preventing overheating caused by poor contact.

 

3. Strongly corrosive chemical industry and marine environment: The inherent corrosion resistance of red copper enables it to be used stably for a long time in the connection and sealing of pipe flanges and instrument valves in chemical equipment, ships and offshore platforms, resisting the erosion of salt spray and chemical media.

 

4. Scientific research instruments and medical equipment: In medical diagnostic equipment such as MRI that require absolutely no magnetic interference, and in the internal structural connections of various high-sensitivity scientific research instruments, it ensures the functional purity and measurement accuracy of the equipment.

 

FAQ

Q1: The total length of this nut is 103mm, but the thread depth is only 17mm. Is the remaining 86mm a polished rod? What does it do?

A1: Yes, your understanding is correct. The rest is a smooth shaft. This extra-long polished rod section mainly plays the role of structural extension, precise positioning and guidance. It can easily pass through multiple components or thick plates to achieve span-distance connections, and provides good support and centering before threading, simplifying complex assemblies.

 

Q2: Why choose copper as the material? What is the difference between it and a brass nut?

A2: The main differences between copper (pure copper) and brass (copper-zinc alloy) are:

Electrical and thermal conductivity: The electrical and thermal conductivity of copper is much better than that of brass, making it a better choice for applications such as power and high-frequency circuits. Corrosion resistance: Red copper has better corrosion resistance in certain media (such as certain acidic environments), and its non-magnetic properties are more stable. Mechanical strength: The strength and hardness of brass are usually higher than those of copper, making it more suitable for general applications that require higher mechanical strength. Therefore, this product is specially designed for scenarios with strict requirements on electrical conductivity, thermal conductivity or special corrosion resistance.

 

Q3: What does the thread specification 1/4-28UNF represent?

A3: This stands for British uniform fine thread. 1/4: The nominal thread diameter is 1/4 inch (about 6.35mm). 28: Refers to the number of teeth per inch per inch, which is a fine thread.
