Product Description

The M3x6x7 screw is a precision metric machine screw designed for robust industrial applications, including automotive, machinery assembly, and electronics. With a nominal diameter of 3mm, 6mm shaft length, and 7mm head height, this M3 hex bolt features a hexagonal drive for secure fastening and optimal torque transmission (1.2–1.5 Nm recommended). Constructed from hardened steel or corrosion-resistant stainless steel, it operates reliably across a temperature range of -50°C to +120°C. Compatible with standard M3 nuts and threaded inserts, it enables direct mechanical connections in structural frameworks without requiring power, communication interfaces, or sensors. Advantages include high tensile strength, durability, and vibration resistance; however, periodic torque checks are recommended to prevent loosening. Not applicable to battery-powered or display-integrated systems, it serves purely as a hardware fastener for modules requiring compact, metric-scale solutions.
