PAN HEAD PHILLIPS SELF-DRILLING SCREWS Product Profile / 十字圆头钻尾螺丝产品简介
1. English Version | 英文版
Product Overview:
The Professional Pan Head Phillips Self-Drilling Screw is an advanced fastening solution engineered for high-efficiency assembly in metal-to-metal and metal-to-wood applications. Featuring an integrated drill point, these screws eliminate the need for pre-drilling, significantly reducing installation time and labor costs in industrial manufacturing, HVAC installation, and steel structural assembly.
Manufacturing & Technology:
Structural Engineering: Manufactured from Case-Hardened Carbon Steel (or Stainless Steel 410 for corrosion resistance). The head is cold-forged for maximum torsional strength, while the Phillips drive is precision-stamped to ensure optimal torque transfer and prevent "cam-out" during high-speed installation.
Drilling Technology: The screw features a Ground Drill Point (point #2, #3, or #4 depending on substrate thickness). The flute is precision-milled to efficiently evacuate metal chips, preventing heat buildup and ensuring consistent penetration through structural steel members (up to $5\text{mm}$ thickness).
Surface Engineering: Treated with High-Performance Zinc Plating ( 8um) or Ruspert/Ceramic Coating for extreme salt-spray resistance. This finish ensures compatibility with modern building materials and prevents galvanic corrosion.
Operational Design: The pan head design provides a large bearing surface for secure clamping, making it ideal for attaching thin sheets or clips where a low-profile yet secure hold is required.
Technical Parameters:
Material: Carbon Steel (C1022) / Stainless Steel (SS410).
Drive Style: Phillips (PH #2).
Diameter/Length: 3.5mm - 6.3mm / 13mm - 100mm.
Standard: Compliance with DIN 7504N or ISO 15481.
