Application -- Hex nut expansion is widely used in fence, burglarproof doors and window, canopy, air conditioning rack fixation, home decoration, engineering, etc.
Easy to Install -- Hex nut expansion comes with nuts and washers. Concrete anchor and masonry anchor, easy to be mounted. The expansion screw is a solid structure, and the punch is formed at one time, with a large bearing capacity and extremely strong tensile strength; the expansion pipe is cut by seamless steel pipe, which has a large tensile force after expansion, which is strong and safe.
Warm Tips -- Expansion bolts must be installed on a relatively hard base plate, and the soft and easy to fall off places are unstable, such as the gap of the lime soil of the wall. All expansion pipes should enter the wall. As long as the threaded part is long enough, the sleeve part will be deeper and stronger
