Use these nuts to attach the guide rails we sell on the website. The nut can be attached from above so you don’t have to turn the board underneath. The nut has coarse threads that are screwed into a 6mm hole using a 4mm Allen key or screwdriver, then you can thread both the consumable table and the rail with M4 screws. The nut holds for normal use of the clamps. If the nut loses its hold (which it shouldn’t), you can also fasten the nut from the back just like with a weft nut as the picture at the bottom shows.
