Three Practical Methods For Stainless Steel Threaded Fasteners To Prevent Loosening

As we all know, the fastener is a kind of part that plays the role of connection. Therefore, the anti-loose of fasteners is an important issue. As a professional fastener manufacturer, Xinchi Fastener Company has many years of experience in the fastener industry. We are happy to share fastener knowledge, such as the stainless steel threaded fastener connection method. Generally speaking, there are three basic types of anti-loosening methods for the connection of stainless steel threaded fasteners: non-removable anti-loosening, anti-loosening of mechanical fasteners, and anti-loosening of increasing friction.

Non-removable anti-loosening

This is a method to change the detachable thread connection into a non-detachable thread connection by means of welding, bonding, or impact riveting. Non-removable anti-loosening is a very reliable method of traditional loosening control. Its disadvantage is that threaded fasteners can not be reused and are difficult to operate, so it is often used in some important occasions requiring high reliability and no disassembly.

Anti-loosening of mechanical fasteners

This method is to use mechanical fasteners to fix and pin tight between the threaded parts and the connected parts or between the threaded parts and the threaded parts to stop loosening. The advantage of the mechanical fastener method is that it is reliable, which generally depends on the static strength or fatigue strength of the mechanical fastener (or fastener itself, such as slotted nuts). Its disadvantage is to increase the weight of the fastening connection, the manufacturing, and installation process is more troublesome, can not be mobile installation, so the cost is higher. However, due to the high reliability of mechanical fastener, it is still widely used in some important parts of mechanical products and aerospace products.

Anti-loosening of increasing friction

This method is to increase the friction between the thread or the bolt (screw) head and the nut end face or increase the friction of both, to achieve the purpose of anti-loosening. The increased friction method is less reliable than the above two methods, but its biggest advantage is that it is not limited by the use of space, and can be repeatedly assembled and disassembled, as well as mobile assembly. And some of the fasteners (such as nylon lock nuts, and metal lock nuts) have reached a high level of safety. Therefore, this method is most widely used in the machinery manufacturing sector and the aerospace field.
