Core advantages of the product:

1. Self-tapping design, efficient installation: The screw comes with sharp threads, eliminating the need for pre-drilling and tapping. It can be directly drilled into substrates such as plastic, wood, and thin metal, and can be operated using either manual or electric tools, significantly saving assembly time,
2. Nickel plating for protection and strong durability: The nickel plating layer can isolate the air, moisture, and mild acid-base environments, effectively preventing rust and oxidation of the carbon steel substrate. Compared to ordinary black iron screws, it has a longer service life and is suitable for various indoor environments such as dry and mildly humid conditions.
3. Firm and stable fastening, wide adaptability: The self-tapping thread is tightly combined with the base material, providing good anti-loosening effect and less susceptibility to loosening due to vibration. The specifications cover commonly used sizes such as M2-M6, and can be adapted to various base materials such as plastic casings, wooden boards, and thin steel plates (≤1.5mm), with strong versatility.
