Custom black aluminum screws manufactured for OEM applications

Electronics

---

Custom Black Aluminum Screws are widely adopted in electronics for PC components, electronic housings and precision equipment. Aluminum features light weight, while the black finish offers protection and aesthetics. These screws provide high assembly precision and good corrosion resistance without adding extra load to precision components, ensuring stable performance of electronic products.

Automotive

---

Black Anodized Screws are commonly used for lightweight assemblies and interior components in automotive applications. Aluminum delivers prominent weight-saving benefits to reduce overall vehicle mass, and black anodizing creates a consistent appearance. With reliable fastening performance, they meet automotive interior assembly requirements, balancing weight reduction, corrosion resistance and visual quality.

Motorcycle & Bicycle

---

Custom Aluminum Fasteners are widely selected for weight reduction applications on motorcycles and bicycles. Lightweight aluminum effectively cuts down the total weight of the vehicle, and the black coating provides anti-corrosion protection. The fasteners offer secure clamping for frames and accessories, reducing weight while ensuring safe connection of riding components.

Robotics

---

Black Socket Head Screws are applied to lightweight mechanical structures in robotics. The low-density aluminum lessens the weight of mechanical assemblies for smoother equipment movement. Black anodized surfaces are anti-corrosive and wear-resistant. With high precision, they firmly join mechanical parts to suit the frequent motion of robotic systems.

It was carefully packaged and delivered to the clients following a final inspection.

Black Aluminum Screws has unique advantages in thermal management. The thermal conductivity of its base material is about 205 watts per meter per Kelvin, which is much higher than the 16 watts of stainless steel. It can effectively conduct the heat accumulated at the connection points to the heat sink fins or shell quickly. At the same time, the emissivity of the black anodized film in the infrared band is as high as 0.92, which means that the screw itself can serve as an auxiliary radiation heat dissipation surface. In the actual measurement comparison of outdoor LED lamps, modules using this screw reduced the steady-state temperature rise in the core area by about six degrees Celsius compared to ordinary steel screw solutions. This thermal characteristic not only delays the thermal oxidative aging of the sealing ring, but also keeps the resistance of the contact surface stable, because the thermal resistance of each screw is only one-twentieth of that of steel products of the same specification, which is especially suitable for high-heat flux density working conditions inside high-power drives and car chargers.

From the perspective of reliability in long-term vibration environments, after one hundred thousand cyclic load tests, the preload retention rate of black aluminum screws still reaches more than 95% of the initial value. This is due to the low yield ratio and uniform plastic deformation ability of aluminum, which can effectively buffer the loosening trend caused by fretting wear. According to the destructive test on the M6 ​​specification sample, its guaranteed load is about 10.9 thousand Newtons, which is enough to meet the clamping needs of most thin-walled frames and plastic substrates. During actual installation, the lubricating coating can stabilize the thread friction coefficient in the range of 0.1 to 0.15, significantly reducing the torque dispersion. The color difference ΔE value of the black coating after 500 hours of accelerated UV aging is less than 1.5, proving that its appearance durability can meet the requirements for decoration and camouflage in year-round outdoor displays or marine climate environments.
