Product Description

The M3x8x0.5 screw is a precision-engineered M3 metric fastener designed for high-performance mechanical assembly. With a threaded length of 8mm and a fine 0.5mm pitch, this bolt ensures secure, vibration-resistant connections in compact applications. Manufactured from hardened steel or corrosion-resistant stainless steel (optional), it operates reliably in temperature ranges from -40°C to 120°C, making it suitable for automotive, electronics, robotics, and industrial machinery. The screw’s ISO 4762-compliant hex socket head enables tool-driven installation with minimal space requirements. Key advantages include exceptional shear strength, precise thread engagement for delicate components, and compatibility with standard M3 nuts. Potential limitations involve reduced torque capacity compared to coarser-pitch alternatives. Surface treatments such as zinc plating or black oxide enhance durability in harsh environments. Typical applications include PCB mounting, sensor brackets, and miniature mechanism assembly where space constraints demand compact fasteners.
