having used them , hinge repair plates work really well.
Back to the original issue. My first port of call is to look at what I have already to see if anything will work, even though it might not be optimal.
My woodworking bench is fixed from below with coach screws, never used them in manmade board, but can’t see why they wouldn’t work. Bur ordinary screws will resist a large amount of force. I have picked up one of our pine cupboards full of crockery by its top with no issues. A lot of weight only held by a few screws.
