“NUT” FOR THE SCREW

It is known that in friable material such as drywall or particle Board, the screws holding bad and under load falls. However, it will bind details not worse than a bolt with a nut, if properly prepare the hole for the screw with epoxy. For this purpose the screw is pre-coated with any oily grease (tsiatim, grease, vaseline), and in a hole dug in “epoxy”. Then screwed the screw before final curing of the resin several times to twist as if forming for him the thread.
