The requirement of expansion screw to the ground is of course the harder the better, it also depends on the force when you need the fixed object. Choose an alloy drill bit with the same diameter as the expansion screw expansion ring (tube), and place the equipment on the electric drill for wall penetration.

Expansion screws generally refer to metal expansion screws. 2. The wall penetration depth is preferably the same as the bolt length, and then the expansion screw is placed Syringe Mould Suppliers Into the hole, remember: do not pull out the screw, so as to prevent the bolt from falling into the hole when the hole is drilled deeper and it is difficult to take it out. The expansion part all enters the wall, as long as the thread part is long enough, the greater the depth of the sleeve part,

the stronger it is. It is characterized by also including at least one pipe body. 3. The structure of the telescopic screw equipment is specially designed for the equipment telescopic screws in a special environment. The upper end of the pipe body is fixed by the equipment. As long as your length is greater than or equal to the length of the expansion pipe, then the length of the expansion screw left in the ground is equal to or less than the expansion pipe. Expansion screw installation matters 1. About millimeters. Drill 10 MM holes for 3. 2.

In order to make the equipment more convenient to expand the screw, the expansion screw equipment was born. Expansion screws are composed of components such as screws and expansion tubes. 4. How important are expansion screws? What are the precautions for the construction of expansion screw equipment? Let's explain it to everyone below, let's take a look.We need a lot of expansion screws when the equipment is ceiling-mounted.
