Product Description

The M2.5*3*4 is a compact industrial-grade assembly featuring an M2.5 Machine Screw paired with a corrosion-resistant 3mm Stainless Steel Bolt, designed for precision integration into tight mechanical systems. This 4mm Precision Fastener supports seamless connectivity with modular components in high-vibration environments, optimized for applications in aerospace, automotive manufacturing, and microelectronics. Constructed from grade 304 stainless steel, it operates reliably across a temperature range of -40°C to 250°C and withstands mechanical loads up to 12N·m. Its ultra-fine 0.15mm tolerance ensures secure, vibration-proof fastening while maintaining compatibility with automated assembly tools. Key advantages include exceptional durability in harsh conditions and micro-scale adaptability, though installation requires specialized torque-calibrated equipment for optimal performance. Ideal for securing sensitive instrumentation or compact machinery components.
