The Micro precision hexagon socket M1.8 copper nut is a
Mini screw-grade fastener designed for high-density electronics and micro-mechanisms. The whole is made of high-conductivity oxygen-free copper CNC turning, with a thread of M1.8×0.35, a height of only 1.2 mm, and a weight of less than 0.02 g. It can achieve low-resistance grounding in a 0.5 mm thick aluminum-magnesium bracket and is widely used in
Micro Screws such as micromotors and optical modules.
As a key component in the Precision screw family, its hexagon socket opposite sides are 1.5 mm, with a tolerance of h6, and can be locked with a 1.3 mm screwdriver to achieve zero slip angle; the surface is nickel-plated + sealant, the contact resistance is <1 mΩ after 72 h salt spray, and the residual torque of the pre-coated microcapsule glue is attenuated by <2% after 10⁶ vibrations, ensuring long-term looseness.
After passing ASTM F837 certification, the copper nut can directly serve as a conductive node of
Aerospace Micro Screws and be used in CubeSat payload boards and drone flight control ground grids. It maintains ultra-low impedance and reliable locking in an environment of −55 °C~+150 °C and 20 g vibration, providing dual protection of electromagnetic compatibility and structural safety for lightweight spacecraft.
