Product Description

The M3x7x5 metric screw, also known as an M3x7x5 machine bolt or M3x7mm precision fastener, is a compact, threaded component designed for secure fastening in precision mechanical assemblies. This ISO-standard fastener features a 3mm nominal diameter, 7mm shaft length, and 5mm thread engagement depth, optimized for low-profile applications. Constructed from hardened steel with optional corrosion-resistant coatings, it operates reliably across industrial temperature ranges (-30°C to +120°C) and withstands vibration in automotive, robotics, and electronics manufacturing. The fine-pitch threading ensures precise torque transmission up to 4.6Nm while maintaining alignment stability. Key advantages include space-efficient design, repeatable installation accuracy, and compatibility with automated assembly systems. Limitations include reduced shear strength compared to thicker fasteners. Typically employed in panel mounting, sensor brackets, and PCB retention, its standardized dimensions facilitate seamless integration with M3 nuts and threaded inserts.
