Cup Head Square Neck Bolt DIN 603

 Round head square neck bolts under the DIN 603 standard, often also known as carriage screws or guardrail bolts, are a type of fastener with specific design and functional requirements. DIN 603 bolts have a round head design and square neck construction. This design enables the bolt to provide a more uniform and stable tightening force during the connection process. DIN 603 round head square neck bolts are widely used in highway guardrails, breeding guardrails, marine aquaculture, wind power generation and other fields. In these applications, bolts are required to withstand complex forces and environmental conditions, requiring good reliability and durability. In addition to their basic fastening functions, DIN 603 bolts have some unique advantages and features. For example, its round head design reduces damage to the connection surface, while its square neck structure improves the bolt's shear resistance and stability. In addition, this bolt also has good disassembly and reusability, making it easy to maintain and replace.
