Product Description

The M3.5x8x0.5 is a compact metric machine screw designed with M3.5x8mm micro screws geometry and 0.5mm pitch precision threading for secure fastening in confined spaces. Manufactured from corrosion-resistant stainless steel, it operates reliably across temperatures from -40°C to 120°C, ideal for industrial automation, precision electronics, and medical equipment requiring vibration-resistant mounting. Its 0.5mm pitch ensures ultra-fine adjustments and stable mechanical engagement, while the 8mm length balances accessibility in tight assemblies. Though lacking integrated power or communication interfaces, its robust design excels in applications demanding durability, such as optical systems, sensor housings, or PCB mounting. Key advantages include minimal wear over cycles and compatibility with automated tooling, though precise torque control is critical during installation to prevent thread stripping. Suited for environments prioritizing repeatability and resistance to thermal expansion.
