Product Description

Metric hex bolts M12x25 are external hex bolts designed for robust mechanical fastening in industrial applications. These M12x25 metric hex bolts feature a 12 mm diameter, 25 mm length, and a standard external hexagonal head for tool engagement. Constructed from grade 8.8 carbon steel or A2/A4 stainless steel, they offer tensile strengths up to 800 MPa and operate within a temperature range of -50°C to +300°C. The external hex bolts M12x25 support direct integration with flanges, machinery components, and structural assemblies via 19 mm wrench compatibility. Widely used in automotive, construction, and heavy equipment industries, their zinc-plated or hot-dip galvanized coatings enhance corrosion resistance. Key advantages include high shear strength and standardized sizing, while potential limitations involve limited suitability for extreme chemical environments. Torque specifications typically range between 85-95 N·m for steel variants.
