Pan Head Self-tapping Screws

Pan head self-tapping screws are a core type of self-tapping fastener, featuring a round pan head that combines aesthetic appeal with uniform load distribution. These screws can tap and fasten directly into base materials without pre-drilling, greatly improving assembly efficiency. Manufactured in strict compliance with ISO 7049 international standards, product feature 6g-grade thread precision and a smooth, rounded transition between the head and shank, which prevents surface damage during installation and enhances shear resistance. Ideal for securing various lightweight metal components, product offer both practicality and cost-effectiveness as essential connectors in hardware assembly.

Products are widely used in furniture manufacturing, home appliance assembly, architectural decoration, automotive interiors, and electronic hardware components. They can be directly fastened into wood-based panels, plastic parts, thin steel plates (≤1.5mm), and other base materials. In custom furniture assembly, pan head self-tapping screws enable quick positioning and secure fastening of panels and hardware, ensuring stable connections without damaging the material. In appliance production, they are ideal for securing external casings and internal structures, improving overall product sealing and stability. In architectural decoration, these screws are used to fix lightweight ceilings and decorative panels, providing both load-bearing capacity and a clean appearance. Products are indispensable hardware accessories across multiple industries.

Product are made from high-quality carbon steel 1022A or stainless steel 304/316. Carbon steel versions undergo tempered heat treatment to achieve a Rockwell hardness of HRC 28–32 and are surface-treated with zinc plating (ASTM B633) or nickel plating (ASTM B733), providing 48–72 hours of salt spray resistance to withstand humid and corrosive environments. Stainless steel 304/316 variants offer excellent resistance to acids, alkalis, and high temperatures, making them suitable for outdoor or corrosive conditions. All products are ISO 9001 certified, with dimensional tolerances controlled within ±0.02mm to ensure consistency and reliability in batch assembly.

Available in a comprehensive range of standard sizes, product can also be customized for special diameters (up to M8), extended lengths (over 50mm), and specialized surface treatments such as Dacromet and electrophoretic coating to meet non-standard hardware requirements. Packaged in quantities of 500–1000 pieces per pack, they facilitate easy storage and bulk use, making pan head self-tapping screws an optimal choice for improving assembly efficiency and connection stability.
