• High-strength performance delivering 70,000 psi tensile strength and Rockwell B70 hardness for demanding applications
• Secure hex drive engagement with 3mm drive size providing reliable torque transmission and reduced stripping risk
• Consistent threading quality with Class 6g thread fit ensuring reliable fastening and interchangeability
• Full thread coverage along the entire 12mm length for maximum grip strength and load distribution
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These M5 metric flat head screws deliver exceptional engineering value in applications where corrosion resistance and flush surface mounting are critical. The combination of 316 stainless steel material and passivated finish provides superior protection against chemical exposure and saltwater environments, making them ideal for marine equipment, chemical processing plants, and food processing machinery. The undercut flat head profile ensures complete countersinking without head protrusion, while the coarse thread pitch (0.8mm) facilitates quicker installation and better performance in softer materials. The fully threaded design maximizes contact area for enhanced vibration resistance and load distribution, addressing common industrial challenges of joint loosening and material fatigue in dynamic applications.

Specification Summary & Compliance

This M5 x 0.8mm x 12mm flat head screw features precision Class 6g thread fit according to metric standards, with head diameter tolerance maintained between -0.127 to 0.127 mm for consistent countersinking. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial distribution and use. The 100° countersink angle matches standard metric counterbore preparations for seamless integration.
