Functioning
Function: When screwing in a screw, the twist lock prevents the plug from rotating. The internal teeth of the plug ensure secure screw guidance. The plug expands when the screw is screwed in and holds by pressure against the borehole wall. In cavities, the universal plug knots itself.
Installation: The plugs in the Upat assortment box UB are installed using pre-insertion or through-insertion mounting. Create borehole, insert plug. Screw in screw - done.
Tools: Drill, drilling machine, screwdriver / electric screwdriver.
