Product Description

The Golden Flat Head Screw M3-140 is a precision-engineered fastener designed for high-reliability applications in electronics, aerospace, and industrial automation. Featuring a gold-plated finish (Gold Plated Flat Screw M3), it ensures superior corrosion resistance and optimal electrical conductivity. With a 140mm length (Long M3 Flat Head Screw 140mm), it accommodates thick panels or stacked assemblies. Operating within a temperature range of -40°C to +120°C, it suits harsh environments. Ideal for securing sensitive modules, connectors, or PCBs, its flat head design provides flush mounting and minimal protrusion. Advantages include durability, oxidation resistance, and compatibility with M3 threading; however, its extended length may limit use in compact spaces. Commonly applied in high-voltage equipment, communication devices, or precision instruments requiring stable mechanical and electrical performance. Typical torque range: 0.5-0.7 Nm.
