Go to BestBuy or Costco and tell them that you got a TV and it didn't come with the screws. Either open a new box or ask to see the package that the pucks come with and measure the size and pitch of the screw.
You can find the screw pitch finder in many stores including this:

I realize this is an old thread, but it really saved my neck. I have the newest Samsung, the UN65KS9000F. The bottom two tapped insets for the 400x400 VESA mounts were standard M8. No problem. The top two insets would not fit either a M8 or a M6 (although a M6 would turn in just a little.) Customer service was useless. It turns out in the upper holes, you need to screw in the special adapters for the Samsung on-the-wall mount (which I was not using, just a standard VESA bracket.). These adapters give you a standard M8 thread to screw into. The also make up for the difference in thickness, since the top part of the TV is much thinner than the bottom part. Unless I missed it somehow, the manual says nothing about this.

See post below...

Guys - I'm new to this forum, but as someone else has said towards the end, this has been a really useful post. Unfortunately, I'm still stuck as I don't have the wall mount adapters that the TV should have come with (likely misplaced as we're trying to mount the TV a couple years later now), and like you michaelmp6, I've tried various bolts and nothing is working.

How did you end up resolving the problem? Finding the samsung wall mount adapters separately is almost impossible and Samsung customer service is absolutely useless.

Maybe someone out there who is a clever machinist can work this out.

6mm is 0.236 inches. A 6mm screw turns in just a bit, implying that the hole size is close. Perhaps the diameter is right but the pitch is wrong.

[Link: en.wikipedia.org] lists a pitch of 1.0 and a pitch of 0.75 for 6mm screws. Maybe the fine pitch screw is what's needed. My search just now did not find anyone listing that pitch, but it might be out there.

In case American fasteners might work, a couple of rare screw sizes come to mind. A #12 (OD 0.2158") or a#14 (OD 0.2421") screw might just fit.

Search for my rant about mounting 15 Samsung panels in less than a day just before the Fourth of July.

Yeah WARNING the KS Samdungs come with two of these little screws: proprietary male parts on one end and female threads for the reglar screws. Be careful not to throw that shiz away during the unboxing process.

Well just encountered this same issue. Bought my Samsung UN65F8000 a couple of years ago. Decided to mount it on the wall this weekend. Got the bracket on the wall installed and started to install bracket on tv. Bottom screw holes are 8mm but top two don't allow any 6mm that came with kit. Of course I don't have any of the wall mounts pucks from when I got the tv. So what do I use. I found the part number I think AH97-02638A. Looks right but it is no where to be found. Discontinued. Any advice on what to do?

I think the top holes fit a 1/4" bolt with 20tpi thread.

Try these:

Or these if those aren't long enough:

If you have a Lowes or Home Depot nearby, you can stop in and buy 1 bolt instead of ordering a whole box first. And make sure it fits properly.

[edit]: looking back on this thread, yeah you better buy just 1 bolt to check to start. 1/4-20 is pretty common and surely someone would have tried that by now, so that may not be it.

ACE hardware have the best parts selection, along with the odd True Value and old store where the people actually know WTF these parts do.

I don't remember seeing an imported TV that used SAE fasteners.

Nope, they usually all have metric. But it has already been discovered that M6x1 fits but doesn't thread. And someone tried M6x.75 which is the only other metric thread that size (that I know of) and it didn't work either. So it almost has to be SAE and 1/4-20 would be the closest.
This is Samsuck we are talking about :)

Who was that? I found a spec for that thread size but I couldn't find any of those actual screws. Is that what you're remembering?

Ah you are correct, went back and re-read the whole thread and no one has found an M6x.75 yet to try. Someone did try 2 different size 1/4" but they just said coarse & fine, not what the actual pitch was. But I only know of 20 & 28 tpi for 1/4".
Although there was a guy that found some 1/4"-18 on a bunch of 1950s windows once:
[Link: tractorbynet.com]

And that's coarse and fine.

I know something about 1/4-20 because I decided A LONG TIME AGO to standardize on that size. Once I found that an F connector used the same wrench as a 1/4-20, that was it! And Togglers come in 1/4-20 to further clinch it.



Truly oddball. Tractor window bolts.

I know this set is almost 5 years old but i wanted to pass on some information since i'm now mounting this myself. After a lot of (soul) searching, reading threads, experimenting with M5-.75 bolts, etc...

The part number needed for this is:
Samsung BN96-27421A Assy Cover P-Wall Top

It can be readily found on Samsungparts, amazon, sears, etc.

I just ordered it and will update this thread if it's NOT successful.
