Screws are a basic spare parts goods, is a standard hardware class is more common, mainly used in wall installation items as a fixed, many people may be more curious, so expansion screw installation example tutorial is what?
Expansion screw installation example tutorial:
1. Select a drill bit with the same diameter as the expansion ring (tube) of the expansion screw and install it on the electric drill to drill the wall. The depth of the hole is the same as the length of the anchor bolt, and the expansion screw module is lowered into the hole together. Do not screw off the screw, to avoid the hole drilling is relatively deep when the anchor bolt fell into the hole and not very good to take out.
2, tighten the screw 2-3 buckle, feel the expansion screw is tight, and then twist the screw, and then fix the fixed items with holes in the connecting parts pointing to the anchor bolt, install the outside gasket or spring gasket to screw tight.
3. Make 10MM holes for 6MM; Make 12MM holes for 8MM, and make wall holes according to the diameter of the expansion tube. If the wall is too soft, choose a small twist drill. Expansion tube part to all into the wall, only a part of the screw long enough, waterproof sleeve part of the heavier the stronger.
4. For more convenient installation of expansion screws, expansion screw installers are used for it. The construction of the expansion screw installer is designed for the installation of expansion screws in special environments, including a hexagon barrel with an internal interface compatible with the expansion screw, and its characteristics depend on, including at least one section of the tube body, above the tube body fixed to install the hexagon barrel; The upper end of the tube body is provided with an impact drill installation position. It can bind the impact drill to the overhead application, and quickly tighten the installation of expansion screws or swelling screw 3-6 meters from the floor.
