Hex nuts fit onto machine screws, coach bolts and hex bolts. If they are tightening up to timber then a washer should be used. Nylock hex nuts can be used if the item being bolted is to be used over a long period of time or if it is to be subject to a lot of movement.

All the fixings referred to above come in various gauges and lengths. Nails are referred to by there length and head shape i.e. a 50mm wire nail. The bolts are referred to by their gauge, length and type i.e. an M10 X 50mm coach bolt. This is similar to how you describe screws.

Bolt plates are fitted onto timber where coach bolts are repeatedly re-using the same hole. They are mainly used on touring sets where the flats and scenery are constantly being assembled and disassembled. Basically they reinforce the square hole that stops the bolt from spinning when the nut is being tightened.
