Professional Applications & Engineering Value
This M4 flat head screw is engineered to solve critical sealing challenges in industrial equipment, machinery, and fluid systems. The combination of 18-8 stainless steel and a passivated finish ensures exceptional corrosion resistance, while the integrated Buna-N rubber O-ring creates a reliable seal against high-pressure fluids and gases. The undercut flat head profile allows for a flush mount, eliminating protrusions that could interfere with moving parts or aesthetics. With its fully threaded design and Class 6g thread fit, it delivers consistent clamping force and vibration resistance, making it ideal for pneumatic systems, hydraulic assemblies, and electronic enclosures where leak-proof integrity is non-negotiable.
Specification Summary & Compliance
This metric screw features an M4 x 0.7mm thread with coarse spacing and a Class 6g thread fit for precision assembly. It is manufactured in compliance with the DIN 965 standard and fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety standards are upheld for industrial use.
