Product Description

The Flathead CrossM6.3x63 Screw, part of the CrossM Series Fastener lineup, is a precision-engineered M6.3x63 Machine Bolt designed for high-stress industrial applications such as machinery assembly, automotive frameworks, and structural installations. Featuring a flat countersunk head with a cross-recessed drive, it enables flush mounting and secure torque transmission. Constructed from hardened steel with corrosion-resistant coating, it operates reliably within a temperature range of -40°C to +120°C and withstands vibration-intensive environments. Compatible with standard M6.3 threaded nuts and panels, this fastener supports axial loads up to 12 kN and shear forces of 8.5 kN. Advantages include exceptional tensile strength and minimal risk of cam-out during installation, though it requires precise alignment tools for optimal performance. Ideal for heavy-duty equipment and automated production systems requiring standardized ISO metric threading.
