1.What's the difference between fine thread and coarse thread?
1):The pitch of coarse teeth is large, but that of fine teeth is small. 2): The strength of coarse teeth is high, and the fine teeth are well sealed. 3): The thread of coarse teeth has stronger anti-fatigue ability, which is convenient for frequent disassembly, and the fine teeth have strong self-locking ability, large bottom diameter and strong static load capacity.
2.What is the difference between fine teeth and coarse teeth in application?
Fine-threaded and coarse-threaded screws are used for fastening. Fine-threaded screws are generally used to lock thin-walled parts and parts that require high vibration resistance.
