M2 Tap for “chasing” the threads for the Upper Axle Height Setting grub Screw
micromark.com/Metric-Tap
M2.0x40 #82321T $12.**Normally, you would also need a Clearance drill bit, (such as creating a new hole for a fixing screw on a Wheel; yet based on experience, it’s easier and faster just to buy a new rim!)
For the Slot.IT Uprights a Clearance Bit is Not Necessary.
Likewise – a pin vise, or a few wraps of tape, is all you need as a holder/driver for tapping plastic.
Yes, a pin-vise works well. The traditional T-handle is overkill, and more difficult house without wobbling.

The plastic pin on the axle insert (the part we all remove) is 1.85mm. Under a mm, so running an M2 grub screw into that hole is most likely causing outward forces on the hole. Asking for a break in those delicate upper loops. If nothing else, the tap and pin vise give you a nice, true ‘start’
