DIN912 M1.6*3 12.9 grade SCN435 cylindrical head hexagon socket machine screw (blackened) is an extremely compact
Mini screw with an outer diameter of 1.6 mm and a total length of 3 mm, but it has the tensile strength of 12.9 grade high-strength steel (≥1220 MPa). The black phosphate film layer not only improves wear resistance and rust resistance, but also reduces reflection in dim environments, making it suitable for precision optics and night equipment. The cylindrical head with a 0.7 mm hexagon socket can achieve high torque locking in narrow cavities, which is a common
Micro Screws solution in micro pumps and sensor housings.
As a Precision screw, the thread accuracy is 6 g and the head runout is ≤0.01 mm; vacuum quenching + low temperature tempering process ensures the toughness of the core, and the pre-coated microcapsule glue can output 4 kN preload at a torque of 0.12 N·m. The residual torque decay after 10⁶ impacts is <2%, which can prevent loosening in the long term.
After passing ASTM F837 certification, this part can be directly used as
Aerospace Micro Screws for CubeSat propulsion valves and drone servo brackets. It weighs only 0.05 g, but can be stably locked in an environment of −55 °C~+250 °C and 30 g vibration, providing the ultimate high-strength and reliable connection guarantee for lightweight spacecraft.
