How To Prevent Screws From Loosening?

Under normal circumstances, the connection of screws and nuts is self-locking. Therefore, they will not loose themselves under static load and little change in operating temperature. However, under the impact, of vibration, or variable load, and when the working temperature changes little, the connection may loosen, affect the work, and even lead to accidents. In order to ensure a safe and reliable connection, effective anti-loosening measures must be taken for the connection of screws and nuts.

As a professional fastener manufacturer, Xinchi Fastener Company has more than ten years of experience in the field of fasteners. We are pleased to introduce how to prevent screws from loosening.

1. The specification and size of fasteners should be selected correctly. Slightly large or small screws perhaps can be used at the moment, but for a long time, will be loose, or locked.
2. Process specially engineered plastics onto the screw. If used in this way, in the process of locking, due to the engineering plastic being squeezed, the screw nut produces a strong friction torque and reaction force, producing the contact of the whole tooth joint, and then providing absolute resistance to vibration, so that the general screw into a permanent strong anti loose screw, so as to completely solve the problem of screw and screw connection loosening.
3. Increase the friction to prevent loosening. This kind of anti-loosening method is to ensure that the screwed threads do not lose pressure due to changes in external load so that there is always friction resistance to prevent the connection from loosening. Anti-loosening methods to increase friction include installing spring washers and using double nuts.
4. Mechanical anti-loosening. This kind of anti-loosening method is to use a variety of stop parts to prevent the relative rotation of thread and parts to achieve anti-loosening. Mechanical locking is reliable, so there are many applications of this method. Commonly used mechanical anti-loosening measures are cotter pin and groove nut, stop washer and round nut, stop washer and nut, joint wire, and so on.
5. Non-detachable anti-loose method. Using positioning welding, point riveting and other methods to fix the nut on the bolt or the connecting piece, you can fix the screw on the connecting piece, to achieve the effect of anti-loosening.
