Fish Scale Expansion M6-M12 Expansion screws three piece gecko bolt

Product Introduction:

The pull-out anchor bolt has a section of the nut structure that can be deformed. When tightening the nut, the screw uses the pulling force on the nut to deform it, and at the same time, the nut is riveted onto the workpiece, and then the nut is fixed onto the workpiece.
How to use:
In daily life, in order to hang objects on the wall, adhesive hooks or hanging them by nailing on the wall are generally used. Of course, nailing on the wall will make the hooks relatively sturdy. Nailing involves directly inserting cement nails into the wall, drilling holes in the wall, embedding expansion anchor bolts, and then screwing the screws into the anchor bolts. By gradually deepening the screws, the expansion anchor bolts are opened, and the outer surface of the anchor bolts is used to generate friction and gripping force with the wall holes, achieving the fixing effect. However, nowadays, more and more buildings are using gray and sand bricks for their walls. Whether directly nailing or drilling holes on gray and sand bricks, due to their softness, they cannot provide sufficient friction and gripping force, making it easy for fixing screws to rotate or even loosen inside the wall. Seriously affecting the effectiveness of use, in order to improve the adhesion of expansion anchor bolts, various types of burrs have been continuously added to the outer surface in existing technologies, but the effect is not very obvious.
