304 stainless steel self tapping screw PA round head cross groove self tapping screw pan head screw wood screw M4/M5/M6

The core advantages of 304 round head cross self tapping screws are "corrosion resistance and durability, safety and scratch resistance, efficient self tapping, and universal adaptability"

1. 304 stainless steel material, strong corrosion resistance and environmental protection: containing a high proportion of chromium nickel alloy, the surface forms a dense oxide film, which can resist environmental erosion such as humidity, mild acidity and alkalinity, outdoor rain and dew. It is not easy to rust in damp scenes such as kitchens, bathrooms, balconies, or non coastal ordinary outdoor environments, and its service life is 3-5 times that of ordinary carbon steel screws; And the material is non-magnetic, environmentally friendly and non-toxic, with no risk of coating peeling off, suitable for auxiliary fixation related to food contact (such as small food equipment shells), children's products and other scenarios that require material safety
2. Round head design, safe and scratch free: The head is a semi-circular spherical surface, with smooth edges and no sharp edges. It will not scratch clothing, skin or adjacent precision parts during daily contact, and its safety is much higher than that of angular countersunk and flat head screws. It is especially suitable for frequent contact scenarios such as furniture, home accessories, and children's toys.
3. Self tapping thread, efficient installation without drilling: Equipped with sharp cutting threads, it does not require pre drilling and tapping, and can directly drill into substrates such as wood, plastic, thin metal (≤ 1.2mm), panel furniture, ecological boards, etc. Both manual screwdrivers and electric screwdrivers can be operated, with smooth torque transmission and significant assembly time savings. It is suitable for mass production, on-site construction, or DIY scenarios.
4. Cross groove drive, easy to disassemble and assemble, not easy to slip batch: The cross groove is accurately positioned and has a high fit with the tool. It is not easy to slip or damage the groove (slip batch) during disassembly and assembly. Whether it is batch assembly on the factory assembly line or personal daily maintenance and adjustment, it can be operated efficiently, reducing construction difficulty and making it easy for beginners to get started
