Hinge Pin Screw Head Indexing

[quote=Dave Suponski;15848]Francis,The screw shoulders all the way to the hinge pin and the threads are very deep already.The proper way to index the screw without removing the hinge pin would be to remove a few thousands at a time from the back side of the screw head. You will be suprised at how much the screw will move with only a few thousands removed. Go slow...a little at a time...checking constantly....--

I have never removed a hinge pin screw, apparently you have and also refit the screw head to get the proper indexing

Francis,No I am not aware of any publication for Parker guns the lists screw sizes.Yes I have had a few hinge screws out.They are an extra fine thread a little over .250 in diameter if memory serves....
