Causes And Solutions For Slipped Teeth On Screws

As a fastener, the most important thing is of course to be "tight" and "solid", and the thread is the most direct and important reason for the tightness of the screw. It is not uncommon to see screws with slipped teeth, but what are the reasons for this?

One is that the length of the screw is not long enough to fill the screw pit, so the threads in the pit will not match those of the screw and will therefore slip; the second is that the screw is not hard enough to screw into the screw and the teeth will be easily damaged; the third is that the screw has been screwed beyond the standard load of the screw and the screw's own threads or the threads of the screw hole will be damaged; the fourth is that the screw hole and the screw's threads themselves do not correspond; fifth, the outer diameter of the tooth is small and the screw pit is not filled laterally, resulting in slipped teeth.

There are many solutions to these five causes, for example: you can pad the screw head with some thin sheets (such as paper or cotton), which will increase the friction, but this will damage the screw's threads for some of the softer screws, which are screwed in this way twice. Of course, in order to reduce the error of this screw hole grain teeth, you can also use glue into the screw hole, and so on when the glue dries, the mutual thread check will be made up, the consequences are also conceivable, once screwed into, not removable, and if you have to force the removal, the screw teeth will be damaged, the next time you want to screw in again to be not so easy, may have to weld up. Another option is to use an electric drill to enlarge the threads. Since the threads cannot be restored, they are destroyed and reground and replaced with a larger screw. This makes it look "new" again.
