Full Threaded Stud Is Best To Be Stable
-
In the process of using Full Threaded Stud, sometimes loosening occurs. If we are not paying attention at this time, some accidents are prone to happen. Therefore, we should take corresponding measures. Let us learn how to prevent bolts from loosening.
- Non-detachable anti-loose
This is an anti-loosening method that changes the detachable threaded connection into a non-detachable threaded connection by welding, bonding or punching riveting, etc. It is a very reliable traditional anti-loosing method. The disadvantage is that threaded fasteners cannot be reused. And the operation is troublesome. It is often used in some important occasions that require anti-loose and high reliability without disassembly.
- Anti-loosening of mechanical fixing parts
The mechanical fixing part is used to fix and pin between the screw part and the connected part or between the screw part and the screw part to prevent loosening. The advantage of this method is its anti-loosening reliability. Its anti-loosening reliability generally depends on the static strength or fatigue strength of the mechanical fixing parts (or the fasteners themselves, such as slotted nuts). Its disadvantage is that it increases the weight of the fastening connection, is troublesome to manufacture and install, and cannot be installed by motor, so the cost is relatively high. Because of its high reliability, it is still widely used in some important parts of mechanical products and aerospace products.
- China Fastenersincreases friction to prevent loosening
The purpose of preventing loosening can be achieved by increasing the friction between the threads or between the bolt (screw) head and the end face of the nut, or increasing the friction of both at the same time. This anti-loose method is less reliable than the first and second methods, but its biggest advantage is that it is not limited by the use space, can be repeatedly assembled and disassembled many times, and can be assembled by maneuvering. Some fasteners (such as nylon lock nuts, metal lock nuts), their anti-loosening reliability has reached a very high level. Therefore, this anti-loosening method is most widely used in the machinery manufacturing sector and the aerospace field.
