Hook Anchor Bolt High Quality Ring Shape Metal Hook For Constructi

The fixing principle of the expansion bolt: the fixing of the expansion screw is to use the inclination of the shape to promote the expansion to produce the frictional binding force to achieve the fixing effect. The screw has a thread on one end and a taper on the other end. There is a steel skin on the outside. Half of the iron cylinder has several cuts. Put them together into the holes made in the wall. Then lock the nut and the nut to pull the screw outwards, pulling the conical degree into the steel cylinder. The tube is expanded, so it is tightly fixed to the wall, and is generally used to fasten protective fences, awnings, air conditioners, etc. on cement, bricks and other materials. The principle of the expansion bolt is to drive the expansion bolt into the hole on the ground or the wall, and then use a wrench to tighten the nut on the expansion bolt. The bolt goes out, but the outer metal sleeve does not move, so the big end under the bolt is fixed. The metal sleeve expands so that it fills the entire hole. At this time, the expansion bolt cannot be pulled out.
