Is there an issue with hinge insert dowels loosening? Ever use a glue before inserting?
From contributor M:
If you are referring to the plastic expansion dowels for hinges, I have been using them for years and they never come loose. I would say it is not even possible. The screws are stuck in the dowel the way a lock nut's nylon ring grips a bolt.
This can happen occasionally with any hinge brand if the door material is very hard and dense (such as maple or hickory). If you are experiencing this, glue may be a good solution.
In the case of laminate doors, if your insertion machine is not correctly aligned with the dowel holes when pressing the hinge in, the sharp edges of the laminate (around the edge of the 8mm hole) may actually shear the ribs on the dowels, reducing the holding efficiency. Check the alignment of the insertion ram with the holes.
If your hinge machine has a bent spindle, this will cause the holes to be drilled slightly out of round. This condition will also reduce the holding power of the dowels.
Plastic expansion dowels are commonly found on the hinge mounting plate. This is a very effective fix for the mounting plate.
