DIN965 M1.2 M1.5 Stainless Steel CSK Phillip Drive Machine Screw Tiny Micro Repair Screw Kit Eyeglass Sunglass Watch Jewelry Repair Replace Micro Screw

This series of mini countersunk machine tooth screws are specially designed for compact spaces and precise assembly scenarios. They are mini-sized fasteners made with an ultra-thin countersunk design, a cross-drive mechanism, and precise machine tooth threads. They are paired with high-quality 304 stainless steel, which is treated with a passivation process to provide natural rust resistance and corrosion resistance. They are dedicated fasteners for connecting miniature components in fields such as electronic devices, small appliances, and precision instruments, addressing the pain points of conventional screws being too large and unable to fit in narrow assembly spaces.

The screw head is designed with a standard countersunk taper. After installation, it can fully sink into the surface of the workpiece, without any protrusions or scratches, and does not affect the appearance of the workpiece or subsequent assembly. The cross slot is compatible with miniature screwdrivers / electric shank heads, with uniform torque transmission, and are not prone to slipping or warping, even for extremely small specifications. The shaft body features precise machine tooth threads, which perfectly match standard nuts / tapped holes, providing a tight and non-slipping fit, and are suitable for various scenarios requiring miniature threaded connections.

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 2-8mm. The head diameter and the size of the shaft have been precisely controlled, making it easy to embed into narrow spaces such as electronic devices and plastic casings, without affecting component assembly or the flatness of the appearance due to excessive size.

Flat head design, combining tightness and aesthetics

With precise conical flat head design, after insertion, the screw head can fully sink into the workpiece surface, without protrusions or hand-scratching, and no additional grinding treatment is required, which does not affect the flatness of the workpiece surface, and is suitable for precision equipment and products with appearance requirements.

Natural stainless steel rust prevention, suitable for humid / complex working conditions

Using 304 stainless steel material with a chromium content of 18%-20%, the surface is treated with passivation to form a dense oxide film, resistant to salt fog, acid and alkali corrosion, not afraid of slight moisture and friction during equipment use, long-term use is not prone to rusting or peeling, and does not easily deteriorate, extending the product's service life.

Cross drive + precise thread, convenient installation, stable engagement

The cross slot is compatible with micro screwdrivers / electric drills, with uniform torque transmission, not prone to slipping or cracking, even for extremely small specifications, it can be stably installed; the machine-tooth thread is formed by CNC rolling process, the tooth shape is regular, the tolerance is strictly controlled, and it is perfectly compatible with standard nuts / tapping holes, the tightening is smooth without jamming, repeated disassembly still maintains stable engagement performance, not prone to slipping or disengaging.

Integrated molding process, stable strength, not prone to fracture

The screw body is made by cold forging integration molding, without welding or splicing, the strength of the shaft is uniform and stable, the tensile and shear performance meets the standards, long-term use is not prone to fracture or deformation, ensuring the reliability of the connection of micro components, 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 stainless steel material is corrosion-resistant to ensure the long-term stable operation of electronic components. The countersunk design does not affect the flatness of the device's appearance.

Small household appliances and electrical appliances scenario

Used for the connection of small household appliances such as electric toothbrushes, hair dryers, and chargers. It is suitable for plastic casings such as ABS and PC. The countersunk design does not affect the appearance of the appliance. The stainless steel material is suitable for humid environments in kitchens and bathrooms, preventing corrosion and rust, and extending the product's service life.

Precision instruments and meters scenario

Adapting to the fixing of the shells and internal components of small precision instruments and meters. The ultra-small size is suitable for the narrow assembly space of the instruments. The bite fit is stable and not prone to loosening, ensuring the accuracy of the instrument operation. The stainless steel material is corrosion-resistant and suitable for humid environments such as laboratories.

Toy and model assembly scenario

Fixing components for remote control toys, assembly models, and figurines. The miniature size is suitable for the narrow assembly space of the models. Installation is convenient and does not damage the model components. The countersunk design does not affect the overall appearance of the model. Suitable for batch production and DIY scenarios by hand.

Automated precision assembly scenario

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