Service HotlineA screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. A drill-tail screw is a screw with a self-tapping drill head on the front end of the screw. The screw is a common invention in people's production and life for thousands of years. According to the application field, it is the first invention of mankind. Drilling screw is a new invention in recent years, also called self-drilling screw. A screw is a common term for fasteners, an everyday colloquial language.
Hexagon nuts are also called hexagon nuts. Generally, there are many types of nuts, such as hexagon nuts, round nuts, square nuts and so on. Some standards for nuts are still relatively clear. Some specifications and size standards, material requirements standards, electroplating standards, etc. are relatively clear. Different types of nuts also have different standards. Let's introduce the specifications and standards of the nuts in detail.
Nuts and bolts are one of the most widely used fasteners in modern mechanical structures. At present, the common metric bolts and nuts are generally trapezoidal in cross-section. The connection between the bolt and the nut is prone to loosening under severe vibration, or even falls off by itself, and the tightening force of the bolt and nut thread is mainly concentrated in the bolt thread and Between the teeth of the first few threads where the threads of the nut are in contact, resulting in loosening of the fastener and sliding pressure of the threads
At present, more rivets are used on car tires. Due to the long-term bumps of the car, traditional equipment is prone to loosening during the use process, which affects safety. The above problems need to be improved on traditional equipment, so how to design a Rivets on car tires, this becomes a problem we need to solve.
At present, the commonly used shaft retaining rings in the market usually include elastic retaining rings and screw locking retaining rings, but they all require tools to be installed and disassembled, which is relatively inconvenient to use.
