Consists of countersunk head bolts, expansion tubes, flat washers, spring mats and hex nuts. When used, you must first use the impact of electric drill (hammer) in the fixed body on the corresponding size of the hole, then the bolt, expansion tube into the hole, tighten the nut to bolts, expansion tube, the installation and expansion between the fixed body Tight into one. Expansion of the expansion of the principle of expansion of screws is to use the pull out of the slope to promote the expansion of friction caused by clamping force, to achieve a fixed effect. Screw head is a thread, a vertebral. Outside the package of a metal, metal cylinder half of a number of incision, put them together thrown into the hole in the wall, and then lock the nut, Luo mother pull out the screw, the vertebral pull into the metal cylinder, metal cylinder was Open up, so tightly fixed on the wall, generally used for fence, rain Peng, air conditioning and other cement, brick and other materials on the fastening.
