KA black plated cross flat head self-tapping screws, full countersunk head self-tapping screws, small screws, M5/M6

The core advantages of self-tapping screws are "concealed and flush appearance, high self-tapping efficiency, and corrosion resistance of the foundation"

• The countersunk head design ensures concealment, flatness, and no protrusions: the head is conical and countersunk, which can be fully embedded into the counterbore reserved on the workpiece after tightening, flush with the surface, without protruding and scratching clothing, skin, or adjacent parts. It has a low visual presence, making the assembly surface neater, especially suitable for visible scenarios. 编辑译文 段落对照 笔记
• Self-tapping threads, efficient installation without drilling: Equipped with sharp cutting threads, there's no need for pre-drilling or tapping. It can be directly drilled into substrates such as wood, plastic, and thin metal (≤1.2mm). Both manual and electric tools can be used, significantly saving assembly time and suitable for mass production or DIY scenarios.
• Black surface, strong adaptability + basic protection: The surface undergoes oxidation and blackening treatment, which, on one hand, allows for compatibility with dark-colored workpieces (such as black plastic and dark wood), reducing the conspicuousness of exposed screws; on the other hand, it forms a basic passivation film, making it more resistant to minor moisture than ordinary carbon steel screws, reducing the probability of rusting and extending its service life.
• Cross recess drive, easy to assemble and disassemble without slipping: The mainstream cross recess design ensures precise positioning and stable torque transmission. It is less likely to slip and damage the slot opening during assembly and disassembly. Whether using a manual screwdriver or an electric screwdriver, it can be operated efficiently, reducing construction difficulty.

Main application scenarios:

1. In the field of furniture manufacturing, it is suitable for assembling panel furniture, solid wood furniture, and customized cabinets/wardrobes, such as fixing wardrobe backboards, installing desk drawer rails, splicing cabinet bodies, and fixing wooden door hinges.
2. Indoor decoration and soft decoration scenes: used to fix indoor skirting boards, decorative lines, mirror hanging lines, wall shelves, lamp bases, curtain tracks, etc.
3. In the field of home appliances and electronic devices, it is suitable for fixing the outer shell of non precision home appliances (such as small fans, humidifiers, set-top box shells), and fastening plastic components inside home appliances (such as air conditioning interior panels, microwave oven brackets).
4. Processing of wooden/plastic products: used for assembling wooden pallets, wooden boxes, toys, as well as fixing plastic shells and accessories (such as plastic storage boxes and plastic brackets).
