    M1917 rear sight spring screw

    Apologies if I should have been able to find this, but have not!! So asking for knowledge about the U.S. Model of 1917 rifle. As per Charles Stratton book, the little screw that anchors the flat spring under the rear sight - he lists it as 0.14" diameter and 37 threads per inch. He writes that the screws are identical for Pattern 1914 and U.S. Model of 1917 rifles. Does anyone know what series of threads that is from - to find a replacement??
    I know the equipment used to make the Pattern 1914 and then the M1917 originally came from an arsenal near Enfield Locks in Englandicon. So, I suspect many of the threading standards were British - not sure if any were "converted" once in USAicon? So, not having any luck identifying what thread series a 0.14" diameter with 37 threads per inch would fit in to - I am assuming that was a "standard" thread series in Britain, but could possibly be unique to the Enfield arsenal as well??

    Been there, done that. This is a "oldie" problem. And the solution is a 4BA screw eased in. Take an ordinary 4BA mild steel screw - not a high-tensile one - of the appropriate length, grease it well and ease it in. In till it sticks, out, grease, in till it sticks, out, grease .... The thread length in the hole is quite short, so the screw will adapt to fit the hole.

    The same method can be used for other "unobtanium" Enfield screws. There is usually a BA or US number screw that can be eased in with a bit of care. For example 2BA for the swivel screws, if I remember correctly (check it yourself first!). Just make sure that the screw material is softer than the hole you are trying to adapt it to!

    I now find that in these days of Allen, Torx, etc, the greater difficulty is to find any kind of plain unplated mild-steel screw with a good old-fashioned slot! For years I have saved all such from small dismantled machinery (typewriters, printers etc). There ARE specialist suppliers, but by the time you have paid for a single screw plus postage you will realize that having a usable screw in your spares drawer is - literally - worth its weight in , if not gold, then definitely silver.
