Product Description

The M3*14*7 is a precision-engineered fastening component designed for robust structural integration in industrial and electronic applications. Featuring M3x14mm screws with an M3x7 thread bolt configuration, these M3 14-7 fasteners ensure secure connections in tight spaces. Compatible with standard M3 threading tools, they support direct integration into modular assemblies across automation systems, machinery frameworks, and compact electronic enclosures. Operating within a temperature range of -40°C to +120°C, these screws offer corrosion-resistant properties for harsh environments. Ideal for high-vibration scenarios like robotics or automotive manufacturing, their M3x7 thread bolts provide enhanced load distribution. Key advantages include a zinc-plated finish for durability and broad compatibility, though precise torque control is required during installation to prevent overtightening. Typical applications span aerospace, embedded systems, and precision instrumentation, where reliable mechanical bonding is critical. Detection alignment features enable accurate positioning during automated assembly processes. No integrated power or display components are included, as these fasteners focus purely on structural stability.
