A 70" TV weighing 35kg is being mounted on stud partition wall using a fixed position TV mount which is 600mm wide. It will hit two studs approximately 230mm apart in the centre of the TV mount. While studs are normally 600mm apart, they are closer together beside a concrete column which is hidden by the plasterboard over it.
The wall has 12.5mm plasterboard over 6mm plywood over the stud partition.
The TV Mount (rated for 100kg) came with 6.3x55mm screws and wall plugs for use in a variety of materials - brick/concrete/wood.
Should I use the included screws or instead use Goldscrew Woodscrews or TurboCoach Coach Screws? If so, what diameter and length would you suggest?
Here's what came with the TV mount. Looks like they suggest driving the screws straight into the wood, however I assume for a screw of this size a pilot hole should be used?
