Screwing hinges and other fittings to plywood
Hi All. Screwing hinges onto timber is okay? When it comes to plywood it isn’t so easy, that is when nuts and screws are handy and there are plenty available, however my favourite choice is 4 BA, but I am fed up with using pliers on one side whilst I screw from the other side. That is where a spanner cannot be beaten. Would some kind Modeller please tell me where I can get my hands on one??? Best wishes Kevin

If you pilot drill the laminate before you put the screws in it will be fine without doing that you will split laminate.

There are screws for plywood. Usually self tapping, coarse thread. Pilot hole helps. Cheap ply will splinter anyway. Drywall screws are a cheap alternative, but will not stand too much torque and need pilot holes. If the ply is thin glue a square or block the other side. Helps spread the load. A 4 BA is a machine screw with fine thread, not meant to go into anything except tapped metal or hard plastic. If you use machine screws and nuts use washers to spread the load. Double nut or loctite.

First post implied the problem was holding a #4 BA nut while attaching a hinge to plywood.
I use a finger wrench from Lee Valley Tools, good for a variety of nut sizes. No longer available unfortunately. Otherwise an adjustable wrench works fine.
