Product Description

The M8x55 metric screws are precision-engineered threaded fasteners designed for robust industrial applications, offering a 55mm length with an 8mm diameter thread. These M8x55 stainless bolts are constructed from corrosion-resistant A2/A4-grade stainless steel, ensuring durability in harsh environments ranging from -40°C to +120°C. Compatible with standard M8 threading, they provide secure connections for machinery, automation systems, and structural assemblies. Widely used in automotive, marine, and construction industries, these M8x55 threaded fasteners excel in vibration resistance and tensile strength up to 800 MPa. While optimized for mechanical stability, their non-conductive properties may require supplemental grounding in electrical applications. Installation typically requires Class 8.8 torque specifications for optimal performance.
