i am trying to lay a door threshold crossing carpet and tile. the floor beneath is concrete. I have tried screwing into the fllo between the carpet and tile - but the screw doesnt hold and can just be pulled out. What is the best way?

Although many people may suggest tapcon screws or things such as this... you need excersize caution... this may damage the carpet if you are drilling through the carpet... the best thing to do would be cut the threshold to file... use something (pencil, nail. etc.) to mark the carpet under the nail holes (in the threshold)... then cut a small piece of the carpet away from where you will be drilling... *(a drill straight through carpet can cause carpet to ravel or pull strings/lines out of the face)*... after you do this... drill a hole with a concrete bit... then install wooden pegs in the hole (you can buy these wooden pegs in hardware/home improvement stores)... drive them in with a hammer... then use your screws... drive the screws into the wood... and this will hold the threshold in place...

use screws called tapcon. You drill the concrete with a hammer drill and concrete bit. Put down an adhesive such as pl400 and then screw the threshold down and use plugs to fill the holes where the screws are or paint the screw heads.
