4-40 Machine Screw Nut

BP-440-NUT
    4-40 zinc plated hex nut.



    • On second thought though, I guess when they label the threadlock nuts #4, #6, etc they're not referring to metric M4, M6. I take it back

    • I bought these thinking they were M3 sized, but the threading is wrong. But hey, they fit the other 4-40 products I bought. 5 stars for being 4-40, minus one for not living up to M3 standards.
