1894 Winchester Takedown Adjustment Screw Size|Restoration, Repair and Maintenance|Forum|Winchester Collector

My son bought an 1894 takedown in 38-55 that was apparently made in 1896.  The takedown joint is loose and had never been adjusted, but when I took of the forend I found that the three takedown screws were removed and missing.  Does anyone know the thread pitch of those three screws or where I might find replacements.  A 10-32 machine screw is close and will thread in about three turns before binding, but is obviously not the correct size.  Any help would be appreciated.
