Pedestal sidetable, oak

The solid oak side table designed by Matti Klenell features a slim tabletop and five spacers that allow the height to be adjusted quickly between 25 and 55 cm.

The surfaces are generally neat, with only a small dark mark. However, the screw mechanism on one spacer is faulty and does not tighten, making it impossible to secure the part. Could it be repaired, for example by gluing?See the pictures. Kindly note, that the item may have traces of handling.
