Non-standard Metric Round Head Bolt

 Non-standard metric round head bolts refer to round head bolts whose specifications, dimensions or shapes do not comply with metric standards (such as ISO, DIN, etc.). Non-standard metric round head bolts can be classified according to different stress states, construction techniques or other characteristics. Non-standard metric round head bolts are often used in situations that require special connection or fixing requirements, such as steel structure engineering, automobiles, motorcycles, and ships. and other machinery and equipment, as well as industries such as electronics, instrumentation, and home appliances. In these fields, non-standard metric round head bolts are used to connect complex parts and play the role of fixing and bracketing. Compared with standard bolts, non-standard metric round head bolts have more flexible specifications and size options to adapt to different connection needs.
