What is the required M8 screw length for mounting a QE55LS03AAU frame TV to a VG-SESB11K studio stand?

NL: 

Ik heb een tweedehands VG-SESB11K studiostandaard gekocht voor mijn QE55LS03AAU frame-tv, maar de vorige eigenaar is vergeten de originele schroevenset bij de levering te voegen, dus ik ben op zoek naar een vervangend paar. Hoewel de LS03A vermeld staat in het compatibiliteitsgedeelte onder de Studio stand-specificaties (https://www.samsung.com/nl/tv-accessories/studio-stand-vg-sesb11k-xc/), kan ik hetzelfde model niet vinden in de installatiehandleiding van de stand (https://downloadcenter.samsung.com/content/UM/202401/20240131103047767/VG-SESB11_VA81-01127A-02_VA_S...), waarin alleen de LS03B (2022) en LS03D (2024) worden vermeld.

Ik heb 2 vragen:

- Kan ik voor de LS03A dezelfde schroeflengte gebruiken als de LS03B (M8L20)? Als alternatief heb ik inbus bouten M8L20 gekocht, omdat ik de Philips-variant nergens kon vinden.

- Heeft de LS03A ook de "Spacer Ring" nodig, zoals de LS03B? Zo ja, hoeveel "standaard" spacer ringen zouden overeenkomen met de ringen die standaard in het studio stand pakket worden meegeleverd?

EN: I’ve bought a second hand VG-SESB11K studio stand for my QE55LS03AAU frame tv, but the previous owner forgot to include the original screw set in the shipment, so I’m looking for a replacement pair. Although the LS03A is listed in the compatibility section under the Studio stand specs (https://www.samsung.com/nl/tv-accessories/studio-stand-vg-sesb11k-xc/) I can’t find the same model in the stand installation manual (https://downloadcenter.samsung.com/content/UM/202401/20240131103047767/VG-SESB11_VA81-01127A-02_VA_S...) which only lists the LS03B (2022) and LS03D (2024). 

I have 2 questions:

- Does the LS03A use the same screw length as the LS03B (M8L20)? I bought some Allen Screws M8L20 as an alternative, as I figured the Philips variant is hard to get hands on.
- Does it also require the “Spacer Ring” as does the LS03B? If so; how many “default” spacer rings would correspond to the rings shipped in the default studio stand package?

From support of a reseller I’ve found it should be the M8L20, but I do need the spacer ring. Anyone that could tell me where to get a replacement of that one, or how wide the spacer should be?

Got it resolved after all:

• Quick Setup guide covers the thread depth (in my case 10-12mm): BN68-12588B-01_QSG_LS03 55-65inch_WW_L06_210706.0.pdf (samsung.com)
• There's a samsung web page on "How to wall mount your TV", where in section "What size bolt do I need", the obvious is stated that the bolt length, should equal the thread depth + wall mount thickness + spacer thickness: How to wall mount your Samsung TV | Samsung Caribbean
• Eventually I went for a M8L25 (as the M8L20 I bought, didn't have the straight cut that is required according to the quick start guide), with about 14 mm of spacer + mount thickness.

So the key is to find the thread depth (and width) from the Quick Start Guide
