  • unertl screws

    I am trying to find out what size screw is needed for the original M40a1 base. I took some from a reproduction mount and they were too large. Thanks

    Unertl ring bolts-
    Allen key: 7/64"
    Head diameter: .222"
    Shank diameter: .135-.136"
    threads per inch: 32
    thread size: 6-32

    The Unertl bases take a special, slotted flat fillister bolt. 6-48 thread size.
    You can take a Marine out of the Corps, but you can't take the Corps out of a Marine.
