Product Description

The M4x12 hex bolts are metric external hexagonal fasteners designed for precision assembly in mechanical, automotive, and industrial applications. These M4x12 external hex screws feature a 4mm nominal diameter, 12mm shank length, and a standard hexagonal head for compatibility with 7mm wrenches. Constructed from corrosion-resistant steel or stainless steel (A2/A4 grades), they offer high tensile strength up to 800 MPa, suitable for load-bearing assemblies. The metric hex bolts M4x12 support standard ISO 4014/4017 specifications with full or partial threading. Typical operating temperature ranges span -50°C to +250°C depending on material. Ideal for machinery, electronics, and structural frameworks, their advantages include secure torque transmission and space-efficient design, while requiring proper alignment for optimal performance. Surface treatments like zinc plating enhance durability in harsh environments.
