The Small head diameter pan head cross screw M2.5 SUS304 industrial micro pump body fastener is a
Mini screw designed for industrial micro pump bodies. Its head diameter is reduced to 3.8 mm, which can be installed flush in narrow cavities; the combination of the pan head and the cross slot supports high-speed locking with an electric screwdriver, and the fine 2.5 mm thread has good self-guiding in the thin-walled aluminum shell, which is a common micro screw solution for micro pumps, valves and other scenarios.
As a Precision screw, the thread accuracy is 6 g, the head runout is ≤0.02 mm, the surface is passivated + electropolished, and it will not rust in salt spray for 96 hours; the pre-coated microcapsule glue layer can reach 8 kN preload force at 5 N·m torque, and the attenuation after 10⁶ pulses is <3%, ensuring that the pump body is leak-free for a long time.
After passing ASTM F837 certification, this part can directly replace
Aerospace Micro Screws and be used in satellite fuel micro pumps and drone cooling modules. It weighs only 0.25 g, but can remain locked in an environment of −55 °C~+150 °C and 20 g vibration, providing reliable and long-life fastening protection for lightweight aerospace fluid systems.
