It does not affect, the door lock anti-theft is mainly the function of the lock cylinder, the anti-theft knob is loose, as long as the lock cylinder inside the door lock is normal, it will not affect the anti-theft function, and the lock cylinder will affect the anti-theft function of the door lock.
There is no good way, you can change to a thicker self-tapping screw and screw it on, but this will not last too long, a year or two. At that time, it will be removed and re-punched in another place, tapped, and the handle should cover both the new hole and the old hole, which will also work. (Drill bit + wire tapping is less than 10 yuan in total).
This brand is not very clear, the anti-theft door brand, Shengtian door industry is doing well, Foshan old brand.
It does not affect, there is a height below, and there is a certain size standard for installing the security door.
Buy a rust remover with a small tube and spray it in.
