I've been asked to anchor aluminum threshold
for commercial doors. About six inches wide, and
runs the width of two 36 inch steel doors. One
half of the threshold is loose, and needs maybe
four or so anchors.

Some how, I remember some blue anchors that look
a bit like drywall screws, but have really aggressive
threads. Anyone know what I need for the job?

Where to find these? Lowe's? Need flat head, so as
not to be a trip hazard. Can't have hex heads.

They are called "concrete screws"

I use them all the time and they are great. Most any H/W store will have
them. (They come in either flat head or hex head)


BTW: Don;t get the ones made out of concrete though (yes another one of
my stupid jokes)

Whew. Glad they are available. Are they near the

I'll use them while I'm with my blow up doll,

They're Tapcons. Available in flat head like a wood screw or in hex head
like a bolt with an integrated washer. Predrill hole in concrete to a
specified size depending on the diameter of the Tapcon.

As others have said, Tapcon is a common brand of concrete screws. If you
haven't used them before, you might want to try them in a similar situation
to your job before you try them in "real life".

There are 2 types. Flatheads, for which you should countersink the
threshold, and hex head which will end up with the head proud of the
threshold. You might not want that, unless there's a track or groove that
will keep them below the surface.

One key tip: Tapcons are essentially a one shot deal. If you spin them in
too fast you can strip the hole. Once you do that, you can't use that hole
again unless you fill it with epoxy or something. You also usually can't
loosen the fastener and tighten it again. Concrete isn't as forgiving as
wood in that regard. It's basically "a screw them down tight and leave them
alone" operation.

I mention all this because the fasteners will be visible. If you mess one
up, you might have to drill another hole in the threshold which will also
be visible.

Use epoxy instead of beeswax. It lubricates on the way in, and helps
prevent pullout later - - - - -.

Have to see if I can find those. Wonder if they
come in flat head? Don't want big cap heads, that
will stick up over the surface of the threshold.

Tapcons (brand of concrete screw) come in blue or black AFAIK. IMO, either
is going to look crummy in a threshold; not only becuse of the color but
because the head will stick up slightly unless you are able to perfectly
countersink them, not always an easy task on thin aluminum.

Let me ask you, how was the threshold originally attached? I'd try to do it
the same way. One way that is common is to lay down a piece of PT, tapcon
it in and attach the threshold to it with smaller wood screws.

One of the best things to turn in tapcons is a brace with appropriate
bit...plenty of leverage, lets you turn in slow and to the proper torque,
That's particulatry important with a threshold because if you torque too
much you are going to deform the (probably) hollow threshold (unless it has
a support under it).

I use "saw wax" cutting lubricant which looks like a big chap stick and
can be pushed out of the tube from one end. I keep a stick in the
toolbox to lube all sorts of cutting tools, drills, self tapping screws
and even drawer slides and sliding windows. You can find it or a similar
product wherever cutting tools and drills bits are sold. ^_^

I've seen those wax sticks, but never quite connected
in my mind. Sadly, as a Mormon, I've been smoking, off
the side of a circle saw blade. So, the saw wax may get
multiple uses, after I finish power screwing.

Not totally sure, how the original fasten.
I do see silver phillips flat head screws
on the original side. Beyond that, not sure.

It's a back door of a store, no customers

And just a wee bit past that, you break off the tapcon. Tapcons are
like drywall screws - if they give AT ALL they snap. Not made to be
used where any lateral stress/movement can occur.

You can get the dual tube anchor adhesive from the industrial supply
house or what I've used for big screws and bolts which it the glass
capsule epoxy that you put into a cleaned out hole then install the
anchor using a drill attachment that breaks the glass tube containing
the epoxy and catalyst which mixes and spreads inside the hole around
the anchor. The epoxy is stronger than the concrete. Hilti uses a
plastic capsule but a number of manufacturers sell a dual tube system
wkich uses a long disposable mixing nozzle. ^_^

I've had pretty good luck on a few just blasting them full of low
expansion (window and door mounting) urethane spray foam. It sticks
like snot to anything and keeps the threshold from depressing/bouncing
as a bonus.. If mounting a new aluminum threshold to concrete, just
get urethane windsheild mounting compound and lay 2 beads on the
(clean and dry) concrete, and drop the threshold in place. It is there
"for the count".

I installed a lot of thresholds when I worked on automatic and
commercial door systems. I used the blue plastic anchors because sooner
or later some Goomba would come along and damage the threshold which
required replacement. The plastic anchors could be dug out easily which
is not the case with those that are glued in. If the screw in the
plastic anchor was stuck, a flat bar can be hammered under the threshold
to pry it up. Think forward. ^_^

Aparently the bees wax "chap stick" might do

The foam stuff sounded like a thing to try, if this
doesn't do. Plenty more cement under the six inch by
double 36 threshhold, if I have to put in more
anchors. If these snap off, or some thing.

Hoping not many goombas, here.

alone" operation.

No, you can take the Tapcon out, and put 2 or 3 tooth picks in the hole and drive the Tapcon back in. The toothpicks will act just like a plastic or lead anchor, pressing against and gripping the rough sides of the hole with soft wood that the Tapcon screw threads will also grip well. Clear any dust out of the hole with a pipe cleaner first, cut the toothpicks to length, and insert them pointy side up so that the screw point automatically finds it's way in between the inserted toothpicks for a uniform grip all around the screw.

While a toothpick might work in concrete for some period of time, I
wouldn't trust it as much as I would in wood. As I'm sure you know, it is
standard procedure is to use treated wood when there will be contact with
concrete. Why? Moisture.

Maybe I might consider slivers of PT wood if I had to R&R a Tapcon, but I
wouldn't trust a standard kitchen toothpick to last in concrete,

Some how, I remember some blue anchors that look

Where to find these? Lowe's? Need flat head, so as

Plastic inserts and stainless steel screws are the only way to go.

If I caught someone using Tapcons on a door threshold, I'd go get my baseball bat and .... oh, never mind.

How about a couple of nylon tye-straps???

Actually, that might not be a bad idea.

Of course, in my lifetime I don't recall ever having to take a Tapcon out
and put it back in. Anything I've attached with a Tapcon was meant to be
permanent, like a sill plate to a concrete floor, wire mesh for parging
cement block, etc.

Now, I have stripped one or two while installing them, but since they were
eventually going to be hidden, I simply drilled another hole nearby and
tried again.

BTW.. I just found this in a FAQ at the website listed below. My assertion
that Tapcons were a one shot deal was based on my experience, not on
anything I had read. I'm glad I found something to substantiate my comment.


Are these cement screws removable?

Yes, they are removable from the hole in which they are installed. However,
reusing the screw in the same hole is not advisable because the holding
values may be decreased or non-existent.

Of course, using some sort of material to improve the "holding values"
might work. Luckily I've never had to try anything like that.

I read the replies. So this is a repair, right?

Remove the screws and have a peek under the TH. Chances there could
be some old silicone caulk and plastic anchors in the holes already
drill in the concrete. Clean all the off well.

Put new anchors in, run a couple of beads of silicone caulk (draft and
water intrusions prevention under the TH).

Buy screws which are the same as present used on the TH being
repaired.

My take is this is not a new install....

I find blowing through a fairly long straw the best way to clean dust out of a drilled hole in concrete. Just be prepared to protect your eyes as the dust really circulates everywhere if you blow vigorously enough to really clear the dust out of the hole.

Cut to length, for the hole? Now you've got a great idea.

I did buy some Tapcons, and two masonary bits. Looked at beeswax, but
it's $5.49, so I'll try candle wax instead.

A friend loaned me an impact driver, so I can rattle the tapcons in.
Job set up for sometime Friday, see how it goes.
