Industrial Micro Electronics Screws Manufacturer

 · TA2: In a Chinese manufacturing context, TA usually refers to a specific Japanese/ISO or domestic head type convention—most commonly a Pan Head (Type A) or a Cheese Head / Binding Head style. Looking closely at the screw heads in the image, they feature a crisp Hexagon Socket (Allen Drive / Hex Drive).

· 镀PVD (PVD Plating / Physical Vapor Deposition): This is a massive selling point for high-end electronics. PVD coating provides an ultra-thin, highly durable, wear-resistant, and chemically stable layer compared to standard electroplating or anodizing.

· 1.0: Refers to an M1.0 metric thread diameter (Precision micro-screw).

· 1.5: Indicates a thread/shank length of 1.5 mm.

· +: Standard Phillips cross recess drive (visible on the screw heads in the image).

· 点胶 (Nylon / Thread-locking Fluid / Patching):This is a critical feature. It means the screws have a pre-applied thread-locking adhesive (the blue patch visible on the threads). It prevents the screw from loosening due to vibration or thermal expansion.

· 黑锌 (Black Zinc): The surface treatment/plating finish.
