Product Description

The product model M4*12*2 features M4 screws with a 12mm length and 12mm machine bolts, complying with DIN 912 hex socket standards for precision fastening. Designed as a high-strength mechanical fastener, it serves critical roles in machinery assembly, automation systems, and industrial equipment requiring compact, corrosion-resistant components. Operating temperature ranges from -30°C to +120°C, suitable for harsh environments. Advantages include hex socket compatibility for tool accessibility, uniform thread engagement, and compliance with ISO 4762 specifications. Potential limitations involve limited axial load capacity compared to larger bolts. Typical applications include CNC systems, robotics, and electronic enclosures. The 12mm length ensures secure connections in tight spaces without protrusion. Materials include grade 8.8 steel or A2/A4 stainless steel variants. Thread pitch adheres to M4x0.7 metric standards. Surface treatments range from zinc plating to black oxide for enhanced durability. Requires proper torque calibration (1.2-1.5 Nm) to prevent stripping. Not intended for structural load-bearing or dynamic vibration applications.
