cabinet hanger to drill into 20mm

thingiverse

Here are the hangers pressed into a 20mm hole. It's best to drill the hole with a Forstner bit. The holders are 8mm deep. There are two versions available: keyhole and wave. You can identify them by the four small markings in the clamping rings, which are spaced every 90 degrees. This allows for precise alignment of the holder. The screw used has a shaft diameter of 2.5mm and a head diameter of 7mm.
