A threshold was purchased from HomeDepot:
The item comes with screws and needs to be fixed into concrete slab. I would like to understand how to properly screw the threshold into the slab. If it were a wood surface I might drill a pilot hole or use a wood screw, however, given that this is concrete, I get one shot at getting this installed correctly. If not then, it creates a whole new set of problems.
- What is the correct procedure to screw the threshold into a concrete floor?
- Is it necessary to drill a pilot hole? The screws are not wide.
UPDATE: screws were misplaced so maybe tapcons may be used
