 Need help looking for a special fastener or glue.

Okay... picture this...
I have a piece of composite decking (trek) that I need to attach to a supporting 2 x 8 beam. Doesn't sound too hard right? 
Here's the catch, the piece can not be drilled through the face/surface of the decking and there's no way come up and screw from underneath.
I'm looking for something that I can screw into the top of the support, then somehow attach the decking. Or, I'd even go with a very strong adhesive. I've tried "liquid nails" but it did not adhere to the composite decking.
Any ideas?
Thank YOU,
Lana

why can't you drill through? you could put plugs in if you didn't want the screw heads to show.
i don't suggest this but what if you could melt the sides with a blow torch and weld the two together?

No way, PL premium is what you want - it's used for gluing on mirrors to walls, and counter tops, and all any other sort of heavy duty adhesive duties you might need it for.
You will never remove the piece whole, if you glue it with PL premium.
(it is an adhesive that comes like a tube of caulking.)

Gorilla Glue. Nuff said. Don't get it on your hands it removes skin.
But really I bet there is a way to screw it.

there's several options in hidden deck fasteners and some of the composite
decking like Trex is already milled to accept most, if the deck boards arent
already cut to accept this style then a biscuit joiner or a table saw are the
best options for making them work. ask the moderately helpful people at
the local home improvement store what they have in hidden fasteners
another type is an under mount fastener, again, there's several styles
this is they type I've used the most, I prefer it because it's metal and less prone to weathering degradation like plastics
http://www.grabberman.com/CatBrowser.aspx?pkey=sKT%2fW5%2bT14JjDgMJa8D6LZ1dZKMJMbII9k98PNCN8%2fU%3d&pval=oj3Wj32k0KoohYhOpCq8%2fg%3d%3d&pIds=bTt%2fqrDlbuPJAFwFI99Ui1dj%2f8fHfhHQrwBRjpPu54Q%3d
as for adhesives, the vast majority I've come in contact with are great
for the short term, the only one I've ever really liked based on results
of installs that were more than 20 years old is CR Laurence M66
polyurethane construction sealant, it takes about 12 hours to set, 3 days
to fully cure and once it's in place it's not coming back up without doing
extensive damage to something whether it's the deck joists, the boards or
you when you try and get it up
M66 comes in several colors including black, bronze, gray, white, tan,
limestone and redwood so it shouldnt be too difficult to find something
that works for your deck color, dark woods would take something like
medium bronze or redwood
http://www.crlaurence.com/apps/sitesearch/search.aspx?searchSource=search-input&query=M66
my experience with this product on tearout, this has always been the end
result, I was tearing out and replacing to ensure that a leak in a school
wasnt due to my work and I didnt set those blocks in the second pic
a couple of things of note of you work with this product, keep plenty of paper towels on hand for cleanup on the caulk tube and try to avoid getting it on anything you arent ready for it to stay on though many solvents will get it off the decking and your hands, it's not coming out of clothing. the most important is the pookie shooter you use, the cheap stamped steel ones wont push this shit without killing your hands
home depot and lowes have a gun that works, they also carry polyurethane
caulks though I've not tested them for the durability of the M66, the
caulk gun you want is their heavy duty high thrust model, it's about $10
but it's the last caulk gun you'll ever buy and it will look something
like this

Gorilla glue is a problem because of its expansion. Composite decking sucks because of how it looks. You most definitely can screw it down through the top. They make special colored ceramic coated screws for it. I don't know about how it will take hidden fasteners, probably perfectly well. I just wouldn't bother with that with fake wood. And leave the glue idea alone.

Hey everyone,
Thanks for all of your suggestions. I think the winner is PL premium. I've been reading up on it and for those who need to glue down plastic/composite decking, it seems to work well. I'll let you know how my test run goes!
Thanks again!

Just an update...
I had used the PL Premium glue, I paid $8.00 for a tube at Home Depot. It worked like a charm! I was able to glue a few pieces of Trex down on top of some pressure treated 2 x 8's
I did a few test runs with some scrap pieces and within 24 hours is was solid.
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Glad to hear it worked out for you. As a contractor it is a dream to use (messy as fuck sometimes..) and shitty to run into...
We recently had to remove a granite counter top that was PL'd to the cabinet below. Needless to say, the counter top came off in pieces.

the CR Laurence M66 is also a polyurethane adhesive/sealant, IME it's better
than the PL Prem and a few bucks cheaper than home depot sells for, if you
look at the pics I posted you can see what that single 3/8" bead resulted in
when pulling out the sill pan that was under the window, 8 windows total and
we ended up using it on the slab because thats where the water was coming in
at... poly doesnt let go

I may have used the CR Laurence M66, the only problem was that I couldn't find it in my area. I still have a little more work to do so I may try to hunt it down but so far my efforts have all been for not

While on the topic of sealants, I could use your advice Pris.
I've been using A product called; BASF Sonolastic NP1 (Link)
We're replacing all the doors on a fairly large townhouse complex. The siding is an exposed aggregate type stucco. We're using the NP1 to seal the door frame/brick moulding to the stucco.
My problem is, tooling it.
I basically work with a bunch of idiots and no one really knows how to use the stuff ... i was told to caulk it on in a large bead and then spray WD40 on my fingers and spread it out (like with latex painters caulk.) This method doesn't work worth a damn, and once you get this stuff on your hands, it needs to be manually abraded off or taken off a heavy solvent :S.
I found laying a bead and then spraying with WD40 and then tooling with my fingers worked fairly well .. but most of the guys don't bother. They just leave a big fat ugly round bead running around the door.
There has to be a better way...
Whats your opinion, Pris?

a question right up a glass man's alley because all the exterior caulking we
do is with polyuretanes and over stucco or some other rough surfaces
to address the cleanup issue, try to locate ITW Dymon Scrubs-in-a-Bucket,
preferably the citrus flavor because not only do they taste better but they
also clean better including getting the stuff off everything but your clothes
just remove the bulk from your finger with a paper towel and use them to
remove the rest... or use Methyl ethyl ketone or debond 2000, the latter can
be found at marine (boating) shops, MEK in paint section of home depot
the debond2000 is actually pretty good at releasing the cured stuff as well
now, for the important part, if you're using the cartridges or the manual
fill gun from the bucket, most people will tell you to pull your bead
when laying it down, ignore those dumb asses, they obviously have no real
experience with caulking. always push your bead, the two reason is you
pretty much tool the bead while you're running it and the second is
because it gives you better sealing by pushing the material into the gaps
the best way to go about it is to first, cut the tip small at an angle,
around 1/4" to 3/8" then grab the tip with the angle down between the
index finger and thumb and let your little finger ride the inside of the
door frame somewhere, the reason for such control on the tip is it allows
you to get much closer to the stucco without having to touch it with the
tip, if you do snag the stucco it's easier to restart without a huge mess,
honestly, you should never have to touch the stuff with your fingers, it's
just too messy
use a good caulk gun (not the stamped shit) with steady, even pressure and
a consistent speed, if you leave a gap, go back to about 1/2" before the
gap and start it again and continue the bead all the way out. I've always
used the push method and always had good results with very little tooling
and clean up. practice someplace inconspicuous like over a door frame
where a little extra is a benefit and always remember to let the tip and a
finger ride the frame just over the stucco
push like this(kinda)
not like this
now if all else fails, hit the local crafts store or walmart and pick up
the best tool for the job, a cake decorators knife or a pallete knife, CR
Laurence sells them for a fortune but the little Wilton ones run about $8.
get one that's about 1/2" across or grind what ever you find to an
appropriate width for the application
now the two most important things to remember when using this product are:
1. with caulk tubes in hand, as the boss if he prefers the white cock or the black cock
2. always refer to the polyurethane sealants as 'pooky'; "hey mac, toss me the pooky", "dont get that pooky on you, it wont come off"
--------------------

Much appreciated Pris, those rags sounds like just what i need, hopefully i can find them at general paint or home depot (where we have accounts.)
Do you have a recommended caulking gun, By the way?
I will probably have my boss buy me one of these: Ergotech caulking gun
I agree fullheartedly with Icelander, btw!
