Professional Applications & Engineering Value

Engineered for demanding industrial environments, these M12 flat head screws provide exceptional value in applications where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition combined with passivated surface treatment creates a robust barrier against chemical exposure, saltwater conditions, and atmospheric corrosion that typically compromise fastener performance. The fully threaded metric design with coarse 1.75mm pitch ensures rapid installation and superior holding power in construction, marine, chemical processing, and offshore applications. The hex drive configuration delivers efficient torque transmission while the flat head profile enables seamless integration where flush surface requirements are critical for safety and aesthetics.

Specification Summary & Compliance

This metric flat head screw features precise M12 x 1.75mm coarse threading with Class 6g tolerance ensuring consistent fit and performance. Manufacturing adheres to DIN 7991 specifications with dimensional accuracy including 24mm head diameter and 90mm length. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for international projects with strict material restrictions. The passivated finish enhances corrosion protection while maintaining the mechanical properties of the underlying 316 stainless steel material.
