Wow, I don't think that is right. !/4" standard threads are 20 and 28.
I'm thinking this may be a 6 mm x 0.8 metric screw.

1/4-32 UNEF is found on Alco miniature toggle switches and model engine glow plugs.

I just checked. 1/4-32 is a standard for UNEF.
UNF is indeed 28 and UNC is 20 though.
I often forget to check for UNEF threads until confronted by one.

Yes, I've seen it on miniature switches, but never in a bolt or setscrew before. Learn something new every day!
