Product Description

The M3x18 machine screws are specialized electronic assembly screws M3 designed for precision PCB mounting and secure component fastening in compact electronic devices. These precision PCB screws M3x18 feature a 3mm diameter and 18mm length with a standard thread pitch, optimized for high-density circuit board applications. Constructed from corrosion-resistant steel with optional insulated coatings, they operate reliably in temperatures ranging from -40°C to 120°C, making them suitable for industrial automation, telecommunications equipment, and automotive electronics. Their precision-machined flat heads ensure flush mounting without protruding edges, while the hex socket drive enables tool-friendly installation. Though requiring precise torque control during assembly, these screws provide vibration-resistant connections for modules requiring stable 12-24V DC power interfaces. The compact design accommodates tight spaces between components while maintaining consistent clamp force across thermal cycles.
