Expansion is created by tightening a threaded bolt which draws a tapered cone expanding a sleeve against the walls of the hole. Widely used in fence,burglarproof doors and window,canopy,air conditioning rach fixation,home decoration,engineering,etc. No rust,no deformation,non-pollution.
How to use: Put the expansion screw into the ground or the hole on the wall and then tighten the nuts of the expansion bolt with wrench. The bolt goes outside while the metal sheath does not move. Thus the bigger head of the bolt will expand the metal sheath, making it fill the whole hole. Now, the expansion screw can not be pulled out.
