Aluminum Alloy Disc Head Plum Blossom Screw

Product introduction

Aluminum alloy pan head torx screws are a kind of fastener made of aluminum alloy material and have a plum-shaped head groove. Its pan-head design provides a larger pressure-bearing surface to help distribute pressure during tightening and avoid pressure loss on soft or delicate material surfaces. Plum blossom grooves (usually Torx sockets) have excellent anti-screwing properties and allow higher torque to be applied. They are especially suitable for situations where compact installation space is required or where the appearance of the screw head is required to be flat. Due to its material characteristics, this product shows obvious lightweight characteristics while maintaining good mechanical strength and corrosion resistance. It is commonly found in weight-sensitive industrial applications such as aerospace models, high-end bicycles, lightweight consumer electronics, optical instruments, and the internal structural assembly of some outdoor sports equipment. In these applications, it not only achieves reliable connection functions, but also effectively controls the weight of the overall component. Its silvery white or anodized colorful appearance is also often considered for visible decorative or marking assembly locations. When selecting, it is necessary to comprehensively consider the torque tolerance limit of the aluminum alloy material and the chemical compatibility of the working environment.

 

Product features

Lightweight and high strength: Made of aluminum alloy, significant weight reduction is achieved while ensuring sufficient mechanical strength. This makes it irreplaceable in areas that are extremely weight-sensitive (such as aerospace models, high-end sports equipment, precision instruments).

 

Anti-rust and decorative appearance: Aluminum alloys are naturally resistant to corrosion, and the surface is usually anodized. This not only further improves corrosion resistance and surface hardness, but also produces rich, stable and beautiful colors (such as black, silver, gold, etc.), which have both decorative and marking functions.

 

Excellent anti-twisting and slipping design: The plum blossom groove type (commonly known as the internal six-shaped groove) provides more stress points than the traditional one-shaped and cross grooves. Its contact surface is more in line with the special bit, which can effectively transmit greater torque and greatly reduce the risk of "sliding teeth" damaging the screw head during tightening. It is especially suitable for precision assemblies that require multiple disassembly or high torque.

 

Large pressure-bearing surface and aesthetics: The pan head design provides a larger head contact area, which can better disperse the pressing force and protect the surface of the soft material being fastened (such as plastic, aluminum alloy panels) from being dented. At the same time, its head has a rounded contour and looks neat and professional after installation.

 

Product application

1. Consumer electronics and digital products: widely used in the casing and internal structure fixation of laptops, tablets, smartphones, cameras and high-end audio equipment. Its lightweight characteristics do not affect the weight of the product. The plum blossom groove provides a precise and reliable disassembly and assembly experience. The anodized colored surface (such as black) can be perfectly integrated with the product appearance to achieve the unity of function and aesthetics.

 

2. Precision instruments and optical equipment: often used in the assembly of precision devices such as microscopes, measuring instruments, optical lens components and medical equipment. Its non-magnetic aluminum alloy material will not interfere with sensitive components, and its high-strength connection and resistance to repeated disassembly and assembly ensure the long-term accuracy and stability of the equipment.

 

3. High-end sports equipment and models: It is an ideal connector for high-end bicycles (especially carbon fiber parts), drones, model aircraft, racing models, and outdoor lightweight equipment (such as headlamps, hiking poles). It can effectively reduce the overall weight while meeting the requirements for connection strength of equipment in dynamic use.

 

4. Car interiors and modified parts: Suitable for fixing car interior panels, audio panels, ambient light bars and various lightweight modified parts. Its beautiful head design and various color options can improve the texture of the interior while avoiding electrochemical corrosion of metal parts.

 

5. High-end furniture and display props: Commonly used in the assembly of aluminum alloy furniture, display cabinets, lighting and commercial display props that require modern design. Not only is it firmly connected, its exquisite screw head is often used as a visible design element to enhance the overall craftsmanship of the product.

 

FAQ

Q: How strong is this screw? Can it be used on key structures?

A: The strength of aluminum alloy screws is significantly lower than steel screws of the same specifications. It is not recommended for critical structural connections subject to high tensile stresses, shear forces, or severe vibration. Its main advantages are lightweight and rust-proof, and it is suitable for light-load structures, housing fixing, decorative parts installation and weight-sensitive precision equipment.

 

Q: What are the benefits of anodizing? Will the color fade?

A: Anodizing treatment can greatly improve the hardness, wear resistance and corrosion resistance of the aluminum alloy surface, and generate an insulating oxide film. Its color is deposited in the pores of the oxide film through electrolytic coloring, so it is not easy to fall off or fade. The color selection is diverse and beautiful. However, avoid strong scratching with sharp and hard objects.

 

Q: Can it be reused?

A: Can be reused to a limited extent. However, be aware that each disassembly and retightening may cause micro-wear to the aluminum alloy threads. It is recommended to check whether the threads are intact at key parts or after repeated disassembly and assembly, and replace them if necessary to ensure connection reliability.
