Application Scenarios
These galvanized cross pan head self-drilling screws are designed for fast and secure fastening in a wide range of materials without the need for pre-drilling. Thanks to their sharp drill tail, integrated washer-style flat head, and corrosion-resistant zinc plating, they are widely used across Southeast Asia, the Middle East, and Africa in both industrial and residential applications. Common use cases include metal sheet installation, wood-to-metal assembly, interior finishing, and electrical fixture mounting:
Metal Sheet Fixing
Commonly used by HVAC and roofing contractors, these self-drilling screws fasten directly into metal sheets up to 2mm thick without pre-drilling. The flat head design sits flush, making them suitable for visible surfaces.
Wood-to-Metal Framing
Ideal for connecting plywood, particle board, or wood panels to light steel frames. The wide pan head prevents the screw from sinking into soft materials and ensures a tight hold.
Interior Installation
Used by interior builders to mount ceiling panels, ventilation grilles, or cable trays. The cross-recessed head allows quick installation using standard PH2 bits.
Light-Duty Shelving & Fixtures
In workshops, storage areas, or homes, these screws are often used to assemble metal racks, brackets, and utility shelves.
Electrical Box Mounting
Preferred by electricians when securing metal switch boxes or enclosures to walls. The drill tail ensures clean penetration and a firm hold in thin gauge steel.
