Chinese Metal Pan Frame Self Tapping Screw

A pan frame head self-tapping screw is a specialized fastener designed for applications that require a low-profile head and the ability to create threads in materials without pre-drilling. It features a pan frame head, which is a slightly rounded head with a flat bearing surface and a reduced head height compared to a standard pan head. This design allows the screw to sit flush or slightly above the surface, providing a neat and aesthetically pleasing finish while maintaining a strong hold.

The key feature of this screw is its self-tapping design, which includes a sharp, pointed tip and cutting threads that enable it to tap its own threads as it is driven into the material. This eliminates the need for separate tapping or drilling operations, making installation faster and more efficient.

Pan frame head self-tapping screws are typically made from high-strength steel and often coated with materials like zinc, galvanized finishes, or other corrosion-resistant treatments to enhance durability and performance in harsh environments. They are commonly used in industries such as construction, HVAC (heating, ventilation, and air conditioning), metal framing, roofing, and electrical enclosures.
