    Ithaca 37 information needed

    I need to know the screw size and thread type of the small screw on either side of the receiver that functions as a lock screw for the screw next to it.
    Thanks--Shuz

    4x40 pitch + thread with given dimensions - - should be easy enough to fabricate one - i would try contacting current Ithaca manufacturer - https://ithacagun.com/internal-parts/ part #51 in list - definitely would never spend $23.00 each + shipping at Numrich - many hardware stores have excellent machine screw assortments -
