Product Characteristics
- Hexagonal head design: The head of the bolt has a hexagonal shape, which is easy to tighten and remove by using tools such as wrenches and screwdrivers, improving the efficiency of installation and disassembly.
- Screw with hole: The screw part of the bolt is designed with holes, which can be easily penetrated into the fuse or cotter pin to play an anti-loosening role. This design increases the stability of the bolt under vibration or impact loads and prevents the bolt from loosening.
- Fine thread: The bolt is designed with fine thread for higher thread accuracy and stronger connection strength. Fine thread can also provide better sealing performance and fatigue resistance, suitable for applications with high connection requirements.
Application
- Mechanical equipment: The bolt is suitable for the connection and fixing of various mechanical equipment, such as engines, transmission devices, machine tools, etc. In these devices, the bolts need to withstand large loads and vibration, and the fine tooth hexagonal head screw with holes provides reliable connection and anti-loosening performance.
- Bridge construction: In bridge construction, bolts are often used to connect the various parts of the bridge. The fine tooth hexagon head screw with hole bolt can provide higher connection strength and better anti-loosening performance to ensure the safety and stability of the bridge.
- Automotive manufacturing: In automotive manufacturing, bolts are used to connect various parts of the car, such as the engine, chassis, body, etc. The fine tooth hexagon head screw with hole bolt can provide reliable connection and anti-loose performance to ensure the safety and reliability of the vehicle.
