DIN912 M3*12 D=5.5 SUS 304 hexagon socket A2-70 screw is a
Mini screw that combines strength and precision. The thin rod with a diameter of 3 mm and a length of 12 mm is matched with a 5.5 mm cylindrical head, which can achieve high torque locking in narrow cavities while maintaining overall lightweight; A2-70 grade SUS304 stainless steel makes its tensile strength ≥700 MPa, and it does not rust in salt spray for 96 h. It is a common
Micro Screws solution in consumer electronics and industrial modules.
As a Precision screw, the thread accuracy is 6 g, and the head runout is ≤0.02 mm; the surface is electrolytically polished and passivated, with a low friction coefficient. The pre-coated microcapsule glue can output 25 N preload at a torque of 1.5 N·m, and the residual torque decay after 10⁶ vibrations is <2%, ensuring long-term anti-loosening.
After passing ASTM F837 certification, this part can be directly used as
Aerospace Micro Screws for satellite payload brackets and drone servos. It weighs only 1.2 g, but can be stably locked in an environment of −55 °C~+200 °C and 30 g vibration, providing the ultimate micro-connection guarantee of reliability and long life for lightweight spacecraft.
