The M5x35mm screws and the low profile nuts helps to hold everything together.

Note the location of the screw on the left and the nut on the right side.

On the right side there are dedicated Hex nuts imprints.

You can glue the nuts in place and then install the screw if it’s easier for you. In the end, when the screw is properly tighten, you can use some glue or some varnish to prevent the screws from getting out.

Lead screw Nut holder

This plastic part is the holder for the Lead screw nut.

It also has dedicated screw hole location for some sets of bearings.

Caution here, do not tighten the screw on the next steps. Both parts are designed in order to have gap left over (0.5mm) between both parts. This will allows you later on to adjust how close the Jaws are to the extrusion profiles. If you tighten the screws here you won’t be able to install the part afterward!
