Product Description

The M3x7x0.8 screws are precision-engineered metric fasteners designed for robust assembly in industrial applications. These M3 machine screws 7mm in length feature a fine 0.8mm pitch thread for secure engagement in thin materials like aluminum or plastic housings. With an M3 diameter, they comply with ISO 4762 standards, ensuring compatibility with standard nuts and threaded inserts. The metric M3 fastener 0.8 pitch is typically constructed from stainless steel (grade A2/A4) or zinc-plated steel, offering corrosion resistance for machinery, automotive electronics, and automation systems. Operating reliably in -30°C to +120°C environments, these screws provide exceptional shear strength (up to 450 MPa) while maintaining compact dimensions. Key advantages include vibration resistance and precise alignment capabilities, though they require calibrated torque tools (recommended 0.5-0.7 Nm) for optimal installation. Common applications include PCB mounting, sensor bracketing, and enclosure fastening in environments demanding metric-standard components.
