DIN912 M3*12 D=5.5 SUS 304 hexagon socket A2-70 screw is a
Mini screw that combines strength and precision. It uses A2-70 grade SUS304 stainless steel, with a tensile strength of 700 MPa and a cylindrical head diameter of 5.5 mm, which can still achieve high torque locking in confined spaces; the hexagon socket slot is precise, and it can be quickly disassembled and assembled with a thin-walled wrench, making it an ideal choice for precision equipment and mini screws.
As a high-precision screw, the thread tolerance is 6g, the head concentricity is ≤0.02 mm, the surface is pickled and passivated + brightly treated, and the salt spray test is 720 h stainless. The 12 mm length matches the 3 mm fine thread, which can provide a zero-gap, zero-loose firm connection on an aluminum alloy housing or a stainless steel bracket.
In the application of
Aerospace Micro Screws such as satellite payload plates and drone servos, this part meets DIN/ISO dual certification, weighs only 0.6 g, has a vibration resistance level of 30 g RMS, and can be continuously locked in an environment of −55 ℃ ~ +250 ℃, providing long-term protection for lightweight and highly reliable structures.
