I was asked to make a WW1 replica coffin. I decided to fasten everything with screws so that it could be dismantled. The big local hardware store had no slotted screws, so I used square drive and recessed them.
Pros and cons: slotted can be cleaned and the slot can be hacksawed. Slotted drivers can be easily ground to fit. Power drivers easily slip off.
Phillips/pozi look nice. Need a sharp pointed tool to clean out the slots. Drivers tend to become unusable.
Square drive. They will stick to the bit allowing one handed, any position working. They are wonderful to use with a power tool. No pre-drilling required unless near the edge. The slot is hard to clean out if filled with paint. Drivers can be ground to fit as they wear.
