M1/M1.2/M1.4/M1.6/M1.7 Black Oxide Tapping Screw Tiny Screws for Electronics Micro Small Pan Head Assortment Kit for Eyeglasses Watches Clocks Mobile Phone

This series of mini-head cross self-tapping screws are specially designed for compact spaces and precise assembly scenarios. They feature an ultra-small specification cross-head structure with a pointed tail self-tapping design, along with a black wear-resistant and anti-rust coating. They can directly be used on plastic parts, thin metal sheets, electronic housings and other substrates, and can achieve quick fixation without the need for pre-drilled holes. The product is made of high-quality carbon steel, with the surface treated by blackening and passivation, offering both anti-rust and wear-resistant properties as well as a low-key matte appearance. They are dedicated fastening components for connecting miniature components in fields such as precision electronics, small appliances, and toy models, addressing the pain points of conventional screws being too large and unable to fit in compact assembly spaces.

Ultra-small and precise dimensions, suitable for narrow assembly spaces

With a micro-sized design, the thread diameter ranges from M1.0 to M2.0, and the length is only 3-10mm. The head diameter and the body size have been precisely controlled, making it easy to embed in narrow spaces such as electronic devices and plastic casings, without affecting component assembly or the flatness of the appearance due to excessive size.

Blackening and wear-resistant coating, providing dual protection against rust and appearance

The surface undergoes high-temperature blackening and passivation treatment, forming a dense protective film, which is resistant to wear and corrosion. It can withstand minor moisture and friction during equipment use, and is not prone to rust or peeling over a long period of use. The matte black appearance is low-key and elegant, suitable for assembly inside electronic devices or black plastic parts, without damaging the overall texture of the product.

Tapered tail self-tapping design, suitable for multiple substrates without pre-drilled holes

The tip of the tapered tail is hardened, with high hardness and low cutting resistance, allowing it to directly drill into ABS, PC and other plastic parts or thin metal sheets. No pre-drilled holes are required for tapping, and the installation is completed in one step, avoiding the cracking of plastic parts and deformation of thin components caused by pre-drilled holes. Suitable for batch precision assembly scenarios.

Cross-head structure, convenient installation without slipping

The contact surface of the disc head is small, making it less likely to damage the surface of the precision workpiece during tightening. The cross slot is compatible with micro screwdrivers / electric screwdrivers, with uniform torque transmission, and is not prone to slipping or cracking. Even for extremely small specifications, it can be stably installed, suitable for manual and automated assembly lines.

Integrated molding process, stable strength and Not prone to breaking

The screw body is cold-drawn integrated molding without welding or splicing. The strength of the rod body is uniform and stable， with adequate tensile and shear performance. It is not prone to breaking or deforming over a long period of use， ensuring the reliability of the connection of micro components and avoiding equipment failure due to screw breakage.

• Precision electronic equipment scenario

• Fixing internal components of mobile phones, Bluetooth headphones, smart watches, and small digital devices, such as PCB boards, plastic casings, and key components. The ultra-small size does not occupy the internal space of the device, the black anodized coating does not affect the internal appearance of the device, and it is also anti-corrosive to ensure the long-term stable operation of electronic components.

• Small household appliances and electrical devices scenario

• Used for the connection of the shells and internal components of small household appliances such as electric toothbrushes, hair dryers, and chargers. It is suitable for ABS and PC plastic shells. The pointed tail self-drilling design does not cause the plastic parts to crack. The matte black appearance is suitable for black household appliance shells, maintaining the overall texture of the product.

• Toy and model assembly scenario

• Fixing components of remote control toys, assembly models, and figurines. The miniature size is suitable for the narrow assembly space of models. The self-drilling design can directly drill into the plastic model parts, without the need for additional drilling, making installation convenient and less likely to damage the model components.

• Plastic parts and small hardware scenario

• Connecting and fixing various small plastic parts, thin metal sheets, such as plastic supports, small hardware accessories, and the shells of precision instruments, etc. Non-pre-drilled installation avoids damage to the base material, and the anti-corrosion coating is suitable for the regular working conditions of small indoor and outdoor equipment.

• Automated precision assembly scenario

• Suitable for automated assembly lines of electronic devices and small household appliances. The micro specifications and stable performance are compatible with automated drill bit operations. The bite stability is not prone to slipping or breaking, ensuring the assembly efficiency and yield of batch production.
