Installation method:
1. Replace it with a larger expansion screw.
2. First put a few pieces of sawdust into the hole, then knock in the expansion screw, and then gradually tighten the nut.
Extended data:
Expansion bolt Installation method of expansion bolt:
Prepare tools/raw materials, hand electric drill and hammer, cross screwdriver.
Choose an alloy drill with the same diameter as the expansion ring (pipe) of the expansion screw, install it on the electric drill and penetrate the wall. The depth of the hole should be the same as the length of the bolt. Then combine the expansion screws into one. Remember, don't tighten the bolt in case it falls into the hole when it is deep enough.
2-3 Tighten the bolts after fastening. If the expansion bolt feels tight but not loose, tighten the bolt and fix the fixture with the bolt hole. Install external washers or spring washers to tighten bolts.
As shown in the figure, a hole of 10MM is drilled at 6MM, a hole of 12MM is drilled at 8MM, and a through-wall hole is drilled with the outer diameter of the expansion pipe. If the brick wall is soft, choose the first place correctly. The expanded part must completely enter the wall. As long as the threaded part is long enough, the deeper the sleeve part, the greater the strength. The drilling diameter is: M6 series expansion screw drilling tool M8; M8 series expansion screw drilling tools are10mm; ; M 10 series expansion screw drilling tools are12mm; ; M 12 series expansion screw drilling tools are14 mm; ; The diameter of the drill hole is 2 mm larger than the diameter of the screw.
