Pack of 25 Prong T-nuts
These T-nuts are installed into the back of the panel (12 to 21mm thickness)
You need to drill a 12mm hole and screw the holds up into the T-nuts with the help of an Allen Key M10
12mm Wood Drill Bit
Drill a hole into the wood. There should be a distance of 15 to 30 cm between each hole. Gently push the t-nut into the hole so the prongs can grab into the wood and then gently tap the t-nuts in with a hammer. Put all the t-nuts into the panel before you put the wal up. Be careful when you screw in the bolt so the t-nut doesn't spin around.
