Hinge Pin Screw Head Indexing

[Richard Flanders]

I think Harry has the right idea. Thin copper sheeting would work well I would think and would act like a crush washer in other applications and allow some latitude for indexing and would hold the screw head in place well. I've always thought the same thing could be done to floor plate screws out of time. I think that thin copper sheeting or even aluminum foil 'washers' could be made with a leather punch and added under screw heads as needed to get them indexed.
