Adapters Manufacturers introduces the installation method of expansion screws:
1. Choose an alloy drill bit with the same diameter as the expansion screw expansion ring (tube), install it on the electric drill, and then drill the wall. The depth of the hole is preferably the same as the length of the bolt.
2. Lower the expansion screw kit into the hole together, remember; do not unscrew the screw cap to prevent the bolt from falling into the hole when the hole is drilled deep and it is not easy to take it out.
3. After tightening the 2-3 buckle of the screw cap, you feel that the expansion bolt is relatively tight and not loose, then unscrew the screw cap, and then align the fixing piece with the hole on the fixed item to the bolt, and install the outer pad Tighten the screw cap with a piece or a spring washer.
