M6*25 Metric External Hex Bolts, High Strength DIN 933 Steel Structural Fasteners

Metric hex bolts M6x25
DIN 933 M6-25 bolts
ISO 4014 external hex screws
Metric external hexagonal bolts M6*25
Metric hex bolts M6x25, DIN 933 M6-25 bolts, ISO 4014 external hex screws. Fully threaded hex head bolts with external hexagon drive. Precision-engineered to meet international standards for industrial machinery, construction, and equipment assembly applications.

Product Description

The Metric hex bolts M6x25, compliant with DIN 933 M6-25 bolts and ISO 4014 external hex screws standards, are precision-engineered fasteners designed for industrial applications in machinery, automotive assembly, and construction. These bolts feature a 6mm diameter, 25mm length, and a hexagonal head for tool engagement. Constructed from high-tensile steel (grade 8.8) or corrosion-resistant stainless steel (A2-70), they operate reliably across temperatures from -50°C to +150°C. Surface treatments like zinc plating enhance durability in harsh environments. Advantages include high shear strength, standardized dimensions for compatibility, and resistance to vibration loosening. Limitations include potential galvanic corrosion in mixed-metal setups without isolation. These bolts connect structural components, panels, and equipment requiring secure, standardized fastening solutions.
