2.9mm x 13mm Pan Head Self-Drilling Screws (Zinc Plated)

ISO 15481 Pan Head Self‑Drilling Screws – Zinc Plated, PH Drive

Designed for rapid fastening in sheet metal and other thin materials, these ISO 15481 screws drill their own hole and secure a strong, flush connection. A cylindrical pan head spreads the load to minimise surface damage, while a cross-recessed PH drive offers reliable torque transfer.

Key Features & Benefits

• Self-drilling tip: These screws cut their own hole and tap into the material, eliminating the need for a pilot hole and speeding up assembly.
• Pan head design: A low, wide head distributes pressure evenly across the surface, reducing the risk of crushing thin material and providing a clean, professional appearance.
• Cross-recessed PH drive: Phillips (Type H) recess allows for secure bit engagement and efficient torque application.
• High-strength steel: Available in carbon or alloy steel with high hardness for dependable fastening in timber-to-metal or metal-to-metal connections.
• Zinc plating: White galvanised (Cr3+) finish protects against corrosion and oxidation, making these screws suitable for indoor and light outdoor use.
• Wide size range: Diameters from ST2.9 to ST6.3 and lengths typically from 9.5 mm to 50 mm cater to various fastening needs.
• Standards compliance: Manufactured to ISO 15481 (equivalent to DIN 7504N), ensuring consistent dimensions and performance.

Applications

• Ideal for professionals in construction, automotive, HVAC, and metalworking who need quick, reliable fastening in thin sheet metal, aluminium profiles, cladding, ducting, or timber-to-metal assemblies.
• Use with a washer if mounting metal to wood to reduce vibration and prevent damage.
