Product Description

The M4x12 hex socket screws, also known as Cylinder head cap screw M4x12 or Metric hex socket screws M4-12, feature a cylindrical head with 4mm nominal diameter and 12mm shaft length. Designed per DIN 912 standards, these ISO 4762-compliant fasteners utilize a 3mm hex key drive and typically employ steel or stainless steel construction. With a 0.7mm thread pitch and M4 metric sizing, they offer 12.9 hardness grade strength for secure fastening in tight spaces. Commonly applied in machinery assembly, automotive components, and electronic device manufacturing, their low-profile head design enables flush mounting. Optimal performance occurs within -50°C to +250°C temperature ranges under vibration-resistant conditions. Key advantages include corrosion resistance and high torque capacity, though installation requires proper alignment of the 6mm wide hex socket. These cylindrical head screws particularly suit panel mounting and precision equipment where countersunk fasteners are impractical.
