Do you know what type it uses? Are they custom, or a standard size / type I can buy elsewhere?

I haven’t seen it the plate but my guess would be M6-1.0 or M8-1.25 bolts. When I bought aftermarket outrigger feet for my Focus 260s to replace the spikes, the threads were metric, easy for me as I work for a fastener company. If I recall they were M6-1.0. In your situation I’d figure they’re the same but quite possibly counter sunk for a cleaner looking finish.

No, they're way bigger than that.

The stand does use M6-1 20mm to bolt the top plate to the column, and for the bottom spikes, but the holes in the bottom of the C20 are much larger, like the diameter of a pencil or more.

Honestly for what the screws are doing there’s no need for anything larger then an M6, so perhaps they’re using M8s, but that seems like overkill personally. I mean 1 or 2 #10-32 screws would be plenty.

I looked at mine and there are "screws" in the bottom. I assume those come out and then are used for the top plate but I'm just guessing.

Describing the "pop": is an electrical noise, very short, it seems a little like a popping fireplace for this i am calling it "pop".

the wire are all cleaned and inserted well. the speakers are both powered by the same power strip.

i dunno what to do. the previous speakers setup i had here (a cheap logitech one) never "popped".
if i use bluethoot and it doesnt pop can it means that is my audio card?

tnx for help everyone! i am really worried!

I have used stainless steel finishing (tumbling) media. Because it's a 430 series stainless, it can be picked up with a magnet. Heavier than sand, though that's a wash because sand compacts more. Spills are easier to clean up, and neater to repackage if you need to ship the stands later.

I was quoted $1.00 per pound, minimum 10 lbs. Plus shipping.

Probably no benefit besides sand being a mess to work with.

Hopefully this picture will help give some useful info.

1. On the sheet of paper is one of the M6-1.00 20mm screws used to screw the top plate to the column. However, I was wrong -- the spikes are not the same diameter, they're thicker.

2. Although the spikes are meant to go into the bottom plate of the speaker stand, the spike fits properly into the threaded insert on the bottom of the Contour 20, as seen in the photo. However, the instruction sheet doesn't say what the diameter or length of the spike is....

So whatever diameter the spike is, that's the correct diameter for the threaded insert. Maybe M8? Does that look about right for those of you who can eyeball these things?

As for length, shorter than the spike is...

It's not. That's the bottom of the Contour 20 that the adapter plate screws to.

They don't come out; those are threaded insert to stick screws in.

Pardon my ignorance of fasteners, but is the length also implied by the spec number?

I noticed that one is 25mm.

I can confirm that, whatever it is, it's >M6, as the M6 screws will just fall into the threaded insert on the bottom of the Contour 20 because the screw hole is too wide for them.

M7 is only popular in India, it’s probably M8 based on what watchnerd just said.

If M6 actually goes in the hole,it will be M8...M7 does not allow enough material for the thread.M6 is the tap drill size for an M8 screw.

Yep, falls right in, stopped only by the width of the head.

How do you guys now this stuff? Are you machinists?
