• Precise and Secure Fastening: Features a Class 6g thread fit and coarse M3 x 0.5 mm pitch for easy installation and a secure, vibration-resistant hold.
• Optimized Head Design: Undercut flat head with a 90° countersink angle allows for a flush, low-profile installation, ideal for space-constrained assemblies.
• Broad Industry Compliance: Manufactured to meet DIN 965 standards and is RoHS 3 and REACH compliant, ensuring safety and regulatory adherence.
• Efficient Drive System: Phillips No. 1 drive enables quick and straightforward installation with common tools, reducing assembly time.

Professional Applications & Engineering Value

This M3 flat head Phillips screw is engineered to solve critical sealing challenges in industrial and engineering applications. The combination of a fully threaded 18-8 stainless steel body and a Buna-N rubber O-ring creates a robust seal that prevents fluid and gas leaks under high-pressure conditions, up to 6000 psi. Its passivated finish enhances corrosion resistance, making it suitable for harsh environments, including outdoor, automotive, and marine equipment. The undercut flat head design ensures a smooth, flush finish, which is essential for aerodynamic surfaces or assemblies where protrusions are not permissible. By integrating the sealing element directly into the metric screw, it streamlines inventory and assembly processes, reducing the total cost of ownership for B2B clients in sectors like fluid power systems, machinery enclosures, and precision instrumentation.

Specification Summary & Compliance

This screw features precise M3 x 0.5 mm coarse threading with a Class 6g thread fit for consistent dimensional accuracy. It is manufactured in compliance with DIN 965 specifications and adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances. The fully threaded design and right-hand thread direction provide uniform clamping force and ease of use in standard applications.
