Z - axis nut trap/tool mount holes question


I’m starting to work on the z-axis assembly and I have a question recording the holes that need to be drilled into the z-axis rails. The instructions state a 5mm to 8mm hole diameter for the nut trap/tool mount bolts. These holes a larger than the bolts supplied in the bundle kit. I’m assuming that this is to allow for alignment adjustments when everything is put together. I going to opt for a 7/32(5.55mm) bit for drilling the holes. Should I go larger or will this do. Note I’m using a drill press.


As long as the holes are in the right spot and larger than the diameter of your bolts you should be good.

Thanks. Also I’m assuming that the holes are not drilled right through the rail.

Nope, just one side.
