Product Description

The M2.5*6*6 is a compact cross recessed machine screw designed for precision fastening in electronics and micro-mechanical systems. As an M2.5 machine screw variant, it features a 2.5mm diameter, 6mm thread length, and 6mm head height, with a Phillips-compatible cross recess for controlled torque application. Constructed from hardened stainless steel (Grade A2-70), it withstands operating temperatures from -20°C to 120°C and offers corrosion resistance. Compatible with M2.5 hex bolt threading patterns, it secures compact modules in PCB assemblies, optical devices, and miniature robotics. The low-profile design supports tight spaces but limits load-bearing capacity. Surface-treated for reduced galling, it ensures reliable conductivity in low-voltage (<24V) environments. Ideal for aerospace instrumentation and medical device manufacturing, this screw combines precision machining with vibration-resistant performance while maintaining compatibility with standard M2.5 threading tools.
