Help identifying screws used in Aphacool Eisblock Aurora Acryl GPX-A for Radeon RX 6800 XT Gaming Trio X

[lunik1]

Hello,

I am having some trouble identifying the screws used to attach the acrylic and heatsink in the Aphacool Eisblock Aurora Acryl GPX-A for Radeon RX 6800 XT Gaming Trio X (though likely used in other products). They are countersunk socket screws/bolts of length ~3/4″, 1/2″, and 3/8″ (inches appear to line up closer than mm). I initially thought they were 5-40 UNC but these are too small a diameter and too finely threaded.

I have attached a photo of the screws in question

Any help is appreciated

We generally use M4x14 hexagonal screws to fix the acrylic body to the copper block.

I think it's a match for the thickness, but it looks a little longer than 14mm. Maybe 20mm?

You only have to measure the thread length without the head.

Ah, I thought countersunk screws like this were measured including the head https://www.accu.co.uk/p/133-how-to-measure-the-length-of-a-screw

Ah... you are right, my fault, sorry. Asked our development team... i was wrong.

Hi,

in this water block and every Eisblock Aurora beside the new RTX40xx and RX7xxx Series we were using M4x14, M4x16 and M4x20mm Screws.
