The core advantages of copper double-pass copper nuts (usually made of brass, with double-pass referring to the through-hole penetrating the entire nut) are "excellent electrical and thermal conductivity, corrosion resistance, anti-magnetic properties, tight engagement, and strong adaptability",

• Excellent conductivity and thermal conductivity, suitable for precise scenarios. The conductivity and thermal conductivity of brass are far superior to those of carbon steel and stainless steel nuts, enabling rapid conduction of current or heat. It is particularly suitable for the fixation of electronic devices (such as circuit boards, connectors), heat dissipation components, and conductive connectors. The dual-through-hole structure without a closed end prevents deformation due to thermal expansion and contraction caused by heat accumulation, and also avoids current retention leading to localized heating, enhancing safety in use.
• Corrosion-resistant and rust-proof + compatible with special medium Copper (brass) exhibits strong stability in atmospheric, freshwater, and mild acid-base environments, being less prone to rust and corrosion. Compared to carbon steel nuts, it requires no additional plating protection and avoids issues such as plating peeling and rusting. It is suitable for use in scenarios like sanitary ware, plumbing (contact with aqueous medium), and mild chemical environments, maintaining its performance and effectiveness even after prolonged use.
• Non-magnetic, suitable for precision instruments/electromagnetic scenarios Brass is a non-magnetic material and does not generate magnetic interference, making it suitable for precision scenarios that are sensitive to magnetism, such as radar, instruments, medical equipment, and electromagnetic shielding components. It avoids the impact of magnetism on equipment accuracy or signal transmission, which is an advantage that carbon steel and some stainless steel nuts cannot replace.
