• Optimized for Secure Fastening: The undercut flat head profile ensures a flush, low-profile installation, reducing the risk of snagging and improving aesthetic finish.
• Precision Thread Engagement: Class 6g thread fit and coarse M2.5 x 0.45mm threading enable quick assembly and strong holding power in various materials.
• Wide Industrial Compatibility: Compliant with DIN 965 standards, ensuring interchangeability and reliability in European and global engineering applications.
• Enhanced Drive Stability: Phillips No. 1 drive allows for efficient torque application with common tools, minimizing cam-out and speeding up installation.
• Regulatory Compliance Assurance: Meets RoHS 3 and REACH regulations, making it suitable for use in environmentally sensitive and regulated industries.

Professional Applications & Engineering Value

This M2.5 metric flat head screw is engineered to address critical challenges in industrial sealing and corrosion management. The combination of 316 stainless steel and a Viton® O-ring provides a robust solution for applications exposed to high pressure, extreme temperatures, and corrosive agents, such as in chemical processing, marine equipment, and automotive assemblies. The fully threaded design and coarse pitch ensure maximum grip and vibration resistance, while the undercut flat head allows for a seamless fit in countersunk holes, preventing leakage points. Ideal for sealing screw uses in pumps, valves, and electronic enclosures, it delivers long-term reliability and reduces maintenance downtime in demanding industrial fasteners systems.
