Hello, Do you know what is the name of these screws inserted in this plastic thing? I'm building a tv table and these screws are supposed to go in the back but I don't see any hole with the shape of this plastic-inserted screws.
Tap the slim tongue into the gap between the back and frame (flat side against the back board) then insert the screw to secure.
As above - these fixings stop the flimsy back panel from popping out the grooves in panels and also gives the unit some improved rigidity Just double check that the unit is square before fitting these and check couple times during the process I would fix the outside ones first once unit is square and then work inwards, just using a hand screwdriver - no pilot hole needed
