X-Axis Kit Ender-3 v3 se screws

Hi guys, I bought the Linear Rail kit of the x-axis and was happy, when it arrived today. As I was assembling it, I recognized that the 6 top screws didn't fit the t-bolts. I messured them with my caliper and the are m3 as listed in the manual. Does anyone know wich screws would be right? Thanks in advance
