PwnCNC's Steel T-Track Nuts are the perfect addition to any T-Track CNC Bed including Onefinity's QCW.
They come in either M5 or 1/4-20 sizes.
If you have a Shapeoko 4 or Pro and want to use these t-track nuts... you'll need the "Spacers" so the nuts line up perfectly within the Shapeoko Pro's t-tracks.
Mention this in the notes and we'll include them free.
For all others who purchased their standard t-tracks... brands like Rockler and others... no spacers are required and these nuts work out of the box.
