The large-diameter pan head provides an enlarged bearing surface, effectively distributing stress and preventing pull-through or deformation in thin sheet materials. Phillips pan head self drilling screws offer a smooth, clean finished appearance, making them ideal for applications with high aesthetic requirements.
The drill point features a standard 60° cutting edge, enabling direct penetration through 0.5-3.0 mm steel plates, galvanized sheets, and color-coated steel sheets without pre-drilling. This design improves installation efficiency by over 50%. For enhanced corrosion resistance in harsh environments, our stainless steel self drilling pan head screws provide superior durability and extended service life.
Full-body thread design conforming to GB 5280 and ASME B18.6.4 standards ensures tight engagement and excellent locking performance. The standard Phillips drive (PH2) is compatible with most electric and pneumatic bits, supporting automated assembly lines. As a core category of pan head self drilling screws, our products offer versatile drive options including Pozi, Square, and Hex Socket for specialized assembly needs.
Carbon steel fasteners are manufactured through surface carburizing and quenching, delivering high surface hardness (HRC 45–55) with good core toughness. They exhibit superior shear and tensile resistance, suitable for applications involving dynamic loads.
Hefeng Group focuses on manufacturing and supplying screws for real construction needs.
