1. In the field of standard parts/fastener manufacturing industry, there are many fasteners connected by bolts and nuts on machinery, and they should be guaranteed to have sufficient preload, but they should not be overtightened. If it is tightened too tightly, on the one hand, the connector will be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, the preload will decrease, and even cause slippage or breakage, and high-quality service.
2. In the field of motorcycle manufacturing industry, there are many fasteners connected by bolts and nuts on motorcycles, and they should be guaranteed to have sufficient preload, but they should not be overtightened. If it is tightened too tightly, on the one hand, the connector will be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, and the preload will decrease, and even cause slippage or breakage. and excellent service
3. In the field of automobile manufacturing industry, there are many fasteners connected by bolts and nuts on automobiles, and they should be guaranteed to have sufficient preload, but they should not be overtightened. If it is tightened too tightly, on the one hand, the connector will be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, and the preload will decrease, and even cause slippage or breakage. and excellent service
4. There are many fasteners connected by bolts and nuts on the steel structure building, and it should be ensured that it has sufficient preload, but it cannot be overtightened. If it is tightened too tightly, on the one hand, the connector will be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, and the preload will decrease, and even cause slippage or breakage. and excellent service
