Brodhead Pietenpol Association

I am having trouble locating 1.5" or 2" structural #6 machine screws on Aircraft Spruce (for attaching my hinges to the wood frame structure). Can anyone help with a part number or link? Thanks for all the guidance so far.

I would have to look when I get home, but I'm pretty sure these are what I used.
