Lo-Root® Screws
Suitable for use in plywood, particleboard, medium-density fiberboard and softwood, these screws are also appropriate for some hardwoods, such as oak and maple. They are heat treated for hardness and lubricated, and the angle and depth of the thread provide excellent holding capability. Recex™ drive, available in pan or flat head. Lee Valley Bronze finish screws ... four stars !
A lovely box but I think the metal hinges an screws don't do it any justice try making wooden hinges they are not that difficult to make. But will set your boxes a world apart from the rest.
