Hey guys I need some help, go figure!

I need to put the threshold back down between my laundry room and garage. It's the metal type that is fastened with screws. This may seem a stupid question but what is the best way to attach this to my new floor tile. Concrete under ceramic floor tiles. I was going to drill holes and then fasten as I would into a concrete slab, but I don't want to crack the floor tiles, besides there will be a lot of foot traffic, so I want this to last. (What screws should I use, etc.) I don't want to do this twice! When I pulled up the threshold before I laid the tiles, it came up VERY easy! Any suggestions?
Thanks for all your help, the new floor and "step" look great!!! I found the Schluter edge in brass!!! VERY NICE! I could not have done this without you guys! Thanks again!

Glad to know the tile turned out good.
Now on to that threshold.SILICONE !!! That's right,silicone.Apply a generous amount to the bottom of the threshold and press it in place.You should have enough that it oozes just a little.Position it where you want it and let it set.I guarrantee it won't come up and if you ever decide to change it you'll have a hell of a time getting it up too!! Use 100% clear.It seems to work the best.

For a finished look if it has screw holes in it just cut the screws off so they won't hit the floor and press them into some silicone in the holes.abra-cadabra......POOF !! DONE.

If you are sceptical try it out first.Put a piece of aluminum or whatever on a piece of tile with silicone and let it set a day or two then "TRY" to pull it off.

Keith is right ...I see the carpet guys doing it all the time. Seems to work well.

It will work, will stick well but it will be elastic with a springy effect. If you want it rigid, as it would be with screws, use epoxy.

Geez, Uri. What if he wanted to change the threshold someday?

Epoxy will ruin the tiles surface if ever the threshold is removed. If your gonna run that risk you just as well drill holes in it.

if both sides of this door is tiled i hope there is an expasion joint under the this threshold. i would sooner see a slab of stone as a threshold. If you purchase metal buy it without holes drill at grout joints, overdrill screw dia..inject epoxy then screw, put weight on.

Tiles in the Garage??? Tileprof, what kind of car do you drive *grin*
Drill into the grout lines (which means you'll have to drill adjoining holes into the threshold) and screw it down. Now if you only have 2 or 3 grout lines available to drill into .... use a bit of silicon on the ends of the threshold for a little extra bond.

I've seen a lot of tile on garage floors over the years, in fact did one in 6X6 quarry last summer.
