    Excellent product. They look exactly right. Once tapped properly to 6-40, they are flawless.

    6-40 SAE Fillister Screws Do Not Fit These Bobbins

    Posted by Brandt on Mar 4, 2022

    Ordered these bobbins which seem nicely made and vintage accurate, but the matching Fillister pole screws with 6-40 threading don't screw into bobbins without extreme force. I think these maybe in fact threaded for different screws.
