Product Description

This DIN 912 M8x55 hex screw is a high-strength cylindrical head cap screw designed for precision fastening applications. Featuring an M8x55 hex key bolt design with a 6mm hex socket, it conforms to DIN 912 standards for dimensional accuracy and mechanical performance. The cap head socket screw M8x55 is typically manufactured from Class 12.9 alloy steel or A4-70 stainless steel, offering tensile strengths up to 1220 MPa and corrosion resistance. Suitable for industrial machinery, automotive assemblies, and structural applications, it operates reliably in temperatures from -50°C to +250°C. Key advantages include flush-surface installation, vibration resistance, and compatibility with standard hex keys, while potential limitations involve accessibility challenges in confined spaces due to its 55mm length. Surface treatments like zinc plating or black oxide enhance durability in harsh environments.
