ISO 4017 is a widely used standard for hexagon head screws, providing basic dimensions for bolts ranging in size from M1.6 to M64. The standard specifies the nominal diameter, pitch, shank length, and thread length of the screw, as well as the overall length, head width, and height, ensuring that it conforms to certain material and mechanical properties, such as tensile strength, shear strength, and hardness.
CE marking is a mandatory conformity marking for products sold in the European Economic Area (EEA), indicating that they meet the essential requirements of all relevant EU directives, such as the Machinery Directive, the Low Voltage Directive, the Electromagnetic Compatibility Directive, and the RoHS Directive. CE marking allows for the free movement of goods within the EEA, as well as improved product safety and consumer protection.
EN 15048 is a harmonized European Standard for non-preloaded structural bolts and nuts, intended for use in steel structures and metal construction, such as buildings, bridges, towers, and cranes. The standard specifies the dimensions, tolerances, materials, and testing requirements for hexagon head bolts, hexagon nuts, and plain washers, used in combination with each other or with other types of fasteners.
