Engineering Efficiency: Why Flange Head Screws Win Discover why integrated flange head screws outperform traditional screw-and-washer combinations. Unlike standard setups, flange screws eliminate washer deformation under load and prevent eccentric stress concentration caused by clearance holes. By removing the extra interface between the fastener and the workpiece, they significantly reduce embedment losses, ensuring consistent clamping force and structural integrity. While specialty washers (like EPDM seals) remain essential for specific tasks, flange screws offer superior reliability for general applications. For projects requiring extra protection, Gorun Screw supplies high-quality SEMS screws and matched specialty washers. Contact us today to optimize your fastening solutions Read More

Flange head SEMS screws offer significant advantages over traditional screws with separate washers, making them ideal for high-efficiency, reliable fastening. Integrated with a one-piece flange, these screws eliminate the need for loose washers—boosting assembly speed by over 40%. The precision-stamped flange increases bearing area, reduces substrate deformation (especially in soft materials like plastic or wood), and enhances joint durability by evenly distributing clamping force. Designed for vibration resistance, they improve anti-loosening performance without additional hardware. The flange also conforms to irregular surfaces—such as corrugated roofing—and can provide sealing when paired with EPDM. Crucially, the entire screw—including the flange—receives uniform corrosion-resistant finishes like zinc plating, Dacromet, or Zn-Ni, ensuring long-term reliability. Perfect for automotive, electrical, and construction applications, flange head SEMS screws deliver superior load distribut Read More
