Professional Applications & Engineering Value
These M8 flat head screws deliver critical engineering solutions where high-strength fastening meets precision requirements. The black-oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C32 hardness for wear resistance in repetitive assembly operations. The fully threaded design with coarse 1.25mm pitch ensures rapid installation and excellent holding power in metal-to-metal applications, while the 90° countersink angle creates flush surfaces essential for machinery, automotive components, and structural assemblies. The hex drive system allows for high-torque installation without cam-out, making these metric screws ideal for production lines requiring both speed and reliability.
Specification Summary & Compliance
Manufactured to DIN 7991/ISO 10642 specifications with Class 6g thread tolerance ensuring precise fit. The M8 x 1.25mm coarse thread configuration provides optimal engagement while the 45mm length offers versatile application coverage. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting industrial safety and sustainability requirements.
