• Versatile partial threading with 12 mm minimum thread length, providing flexibility in clamping and alignment adjustments

Professional Applications & Engineering Value

This M2.5 flat head screw is engineered to address common industrial challenges such as component corrosion, loosening under vibration, and the need for flush surface mounting. The 18-8 Stainless Steel construction, enhanced by a passivated finish, provides exceptional resistance to oxidation and chemical exposure, making it ideal for electronics enclosures, machinery panels, and outdoor equipment. The hex drive ensures reliable torque transfer, reducing installation time and tool wear. With its coarse metric thread and Class 6g thread fit, it delivers secure fastening in materials like aluminum and plastic, minimizing the risk of cross-threading. The 90° countersink angle allows the screw to sit perfectly flush, preventing snagging and maintaining aerodynamic or aesthetic surfaces in automotive, aerospace, and consumer goods assembly.

Specification Summary & Compliance

This screw adheres to DIN 7991 / ISO 10642 specifications, ensuring dimensional accuracy and interchangeability. Threading conforms to Class 6g tolerance for metric coarse threads (M2.5 x 0.45 mm), with a minimum thread length of 12 mm and overall length of 20 mm. The product is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming the absence of restricted hazardous substances and supporting sustainable procurement practices in industrial supply chains.
