Drop in anchor

Internal pressing geckos are used to secure objects to masonry and usually include an internal pressing sleeve and an internal pressing plug. Insert the casing into the drilled hole, use the flat head Screw on top of the internal forcing plug, and then hammer the screw to make the internal forcing plug into the internal forcing expansion part of the casing, so that it is expanded, and finally screw into the casing with the adapted screw to resist the internal forcing plug, so as to avoid the internal forcing plug rebound. It is suitable for fixing screws and inner teeth in heavy load range, installation of fire equipment, hot water pipe air conditioning and exhaust pipe, curtain wall, inverted hanging pipe ceiling, etc.

In order to make the fixation more firm, the surface of the internal forcing casing is usually set with uneven patterns, but the inner wall of the hole is often very rough surface, the effect of the ordinary pattern is very limited, and can not play a good effect of further reinforcement.
