Product Description

The Cylindrical head hexagon socket screw, model M12x45, is a precision-engineered M12x45 hex socket screw designed for robust industrial applications. This M12x45 socket head cap screw features a cylindrical head with an internal hex drive (ISO 4762 standard), M12 thread diameter, and 45mm shaft length. Constructed from high-grade steel or stainless steel (A2/A4 grade options), it operates reliably within -50°C to +150°C and withstands vibration-heavy environments. Commonly used in machinery assembly, automotive components, and structural frameworks, this Cylindrical hex socket screw offers space-saving design, secure torque transmission, and corrosion-resistant surface treatments like zinc plating. Its key advantages include high tensile strength (up to 12.9 grade) and flush mounting capability, though installation requires specialized hex tools (typically 10mm hex key). The compact head design prevents protrusion while maintaining full thread engagement. Primary applications span manufacturing equipment, heavy-duty construction, and precision engineering systems requiring vibration-resistant fastening solutions.
