Color zinc fiber nails are essentially self tapping fasteners that have undergone hardening treatment. They are often made of high carbon steel as the base material and treated with a color zinc coating. They are suitable for multiple scenarios such as woodworking and decoration, and have multiple advantages such as stability and corrosion resistance. The following are their specific advantages

• Corrosion resistant and durable, with strong adaptability to appearance: The colored zinc coating on the surface can form an effective protective layer, enhancing the ability to resist oxidation and rust. Compared with ordinary uncoated screws, it has a longer service life in humid indoor environments; The color tone of colored zinc is similar to that of wood, and it will not appear abrupt after installation, which can maintain the cleanliness and uniformity of the workpiece appearance.
• High hardness and stable fastening: Most of them have undergone heat treatment processes such as carburizing, possessing the characteristics of "soft inside and hard outside". They have high surface hardness, can withstand large torque, are not easy to break or slip during installation, and have good core toughness, which is not easy to deform after loading. At the same time, its thread is thicker, which can quickly drill into the substrate and allow the matching expansion tube to fully expand, greatly improving the biting force with the substrate and enhancing the stability of fixation.
• High cost-effectiveness and convenient use: The material is mostly common carburized carbon steel, which has a lower cost compared to stainless steel fasteners. The specifications are diverse, with diameters ranging from M3 to M8 and lengths ranging from 6.5mm to 150mm. In addition, they are mostly designed with cross grooves or square grooves, which can be operated with ordinary manual screwdrivers or electric screwdrivers without the need for pre drilling and tapping. Whether it is factory batch assembly or on-site construction, it is very efficient.
