CB M1.2 M1.5 Black Oxide Machine Screw Tiny Micro Repair Screw Kit Eyeglass Sunglass Repair Kit with Screwdriver for Repair Spectacles Watch Jewelry

This series of mini blackened head screws is an ultra-small-sized fastener specially designed for precise electronics, small devices, and instrument meters in compact assembly spaces. It features a standard head + cross drive + precise machine thread structure, combined with carbon steel substrate and blackening passivation treatment. It combines wear resistance and rust prevention properties with matte industrial texture. It is a dedicated fastener for connecting micro components inside electronic devices and precision instruments, addressing the pain point of conventional screws being too large and unable to fit in narrow spaces.

The screw head is designed as a standard round head, suitable for semi-sunk installation requirements; the cross slot is compatible with mini screwdrivers / electric bits, with uniform torque transmission, and is not prone to slipping or cracking; the shaft body adopts precise machine threads, perfectly matching standard nuts / tapped holes, with tight engagement and no slippage, suitable for various micro component thread connection needs.

Performance features: Miniature precise size suitable for narrow spaces, blackening for rust prevention and wear resistance, stable thread engagement and not prone to slippage, suitable for precise assembly scenarios

Installation compatibility: Compatible with miniature cross screwdrivers / electric drills, single person can complete precise assembly, compatible with manual tightening and automated assembly line scenarios

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 be inserted into the narrow spaces inside electronic devices and small instruments. It will not affect the assembly of components or the appearance of the equipment due to excessive size.

Blackening and passivation treatment, wear-resistant and rust-proof, suitable for industrial scenarios

The surface undergoes high-temperature blackening and passivation treatment, forming a dense oxide film, with excellent wear-resistant and rust-proof properties. It can resist oil stains and water vapor corrosion in the workshop. The matte black appearance is low-key and elegant, suitable for dark equipment or internal non-exposed scenarios, without affecting the overall texture of the equipment.

Cross-drive + precise thread, easy installation, stable engagement

The cross groove is compatible with micro screwdrivers / electric drills, with uniform torque transmission, and is 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, with regular tooth shapes and strict tolerance control, perfectly matching standard nuts / tapped holes. The tightening is smooth without jamming, and the stable engagement performance is maintained even after repeated disassembly and assembly, without 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, and it is not prone to fracture or deformation 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 Bluetooth headphones, smart watches, and small digital devices, such as PCB boards, plastic casings, and key component assemblies. The ultra-small size does not occupy the internal space of the device, and the blackening anti-rust treatment ensures the long-term stable operation of electronic components. The matte finish does not affect the overall texture of the device interior.

Small household appliances and electrical devices scenario

Used for the shells and internal components connection of small household appliances such as electric toothbrushes, razors, chargers, etc. It is compatible with ABS, PC, etc. plastic shells, and the installation is convenient without damaging the components. The blackened model is suitable for dark household appliances or equipment interior scenarios, maintaining the overall texture of the product.

Precision instruments and meters scenario

Fixing 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, and the bite is stable without loosening, ensuring the operation accuracy of the instruments. The wear-resistant and anti-rust treatment is suitable for humid and oily environments such as laboratories.

Toy and model assembly scenario

Fixing the components of remote control toys, assembly models, and figurines. The miniature size is suitable for the narrow assembly space of the models, and the installation is convenient without damaging the model components. The matte black finish is suitable for dark models, without affecting the overall design style.

Automated precision assembly scenario

Adapting to the automated assembly lines of electronic devices and small household appliances. The miniature specifications and stable performance are compatible with automated drill bit operations. The bite is stable without slipping or breaking, ensuring the assembly efficiency and yield of batch production.
