GB70.1 M2*12 SUS 304 white washed cylindrical head hexagon socket machine screw (without knurling)

GB70.1 M2*12 SUS 304 white washed cylindrical head hexagon socket machine screw (without knurling) is a mini screw that complies with national standards. It is designed for assembly scenarios with limited space but high strength requirements. The M2 thin rod with 12 mm long thread can achieve deep hole locking in thin-walled brackets or stacked circuits; the cylindrical head diameter is only 3.8 mm, and it is matched with a 1.5 mm hexagon socket, which saves head space and is convenient for precision tool operation. It is a common micro screws solution in micro pumps and optical modules.   As a Precision screw, its thread accuracy is 6 g, and the head coaxiality is ≤0.02 mm; SUS304 is passivated and whitewashed, and the salt spray test is ≥96 h. It is non-magnetic and corrosion-resistant. After batch CNC turning, 100% go and no-go gauge detection is carried out to ensure zero clearance with the mother hole. It can output 6 kN preload force at 1.2 N·m torque, and vibration attenuatio…
