Description

First of all these hardwall picture hooks are plastic hooks with metal pins on top that penetrate through the surface of the wall. Furthermore, they are typically used to support objects no heavier than 20lbs or approximately 9kg. Consequently, the objects must exert a downward pull only and not away from the wall.
These molded hooks have short hardened steel pins pre-loaded. Only a hammer is required to drive them into the hardest surfaces. finally, these hooks are made for hard concrete and hard brick walls.
