Drive Size: 2.5mm
Class 12.9 allow steel black oxide
For the Ender 3 Series printers, the M5 x 8mm screw is normally stainless steel. We have replaced our stainless variety with the black-oxide finish hardware and we like how it looks. They disappear into the background (especially in the front of the Ender 3) and it looks much nicer. The Ender 3 uses (4) of these in the front of the printer attaching the cpu/mainboard enclosure and the display panel onto the 4040 Profile base.
