VEVOR 1 Axis Lathe Linear Scale, 850 mm Length, Aluminum Precision Linear Glass Scale, 5 Bearing System for Milling Lathe Machine

Hi, I'm wondering if you can tell me what screws are included in the accessory set for the 1 axis linear scales. They look like M4s, but I just wanted to make sure. I am planning on printing some parts to attach and need to know the hole sizes. Thanks for your help!
