Professional Applications & Engineering Value

This M3 brass flat head screw delivers exceptional engineering value through its combination of corrosion-resistant brass construction and precision metric threading. The fully threaded design with Class 6g thread fit ensures consistent clamping force across the entire 12 mm length, preventing loosening under vibration while the coarse thread pitch enables faster installation in production environments. The hex drive system provides superior torque transmission compared to Phillips or slotted drives, reducing installation time and preventing driver slippage that can damage components. The 90° countersink angle and flat head profile create seamless finishes in machinery, electrical enclosures, and precision instruments where both aesthetic appeal and functional performance are critical. These industrial screws are particularly valuable in applications requiring repeated disassembly and reassembly, as the brass material maintains its integrity through multiple cycles.

Specification Summary & Compliance

This precision metric screw features M3 x 0.5 mm coarse threading with Class 6g thread fit tolerance according to ISO standards, ensuring consistent performance across manufacturing batches. The manufacturing process strictly adheres to DIN 7991 specifications for dimensional accuracy and mechanical properties. Regulatory compliance includes full conformance with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as an alloying element, and current REACH (EC 1907/2006) requirements as of June 14, 2023, making these screws suitable for global distribution and use in regulated industries.
