Button head cap screws

Hello all,



An honest-to-pete metalworking question: what is the diameter and thickness of the head on a 1/4-20 button head cap screw? My web search was fruitless.

Sometimes Google sucks---but I did find it!

.437/.419 dia .132/.122 high

McMaster-Carr has the dimensions in their online catalog. I don't recall offhand whether they show the limits or just the nominal dimensions.

Thanks Bill! I just didn't know how to Google properly, I guess... :-)

Interestingly enough, both of these are probably from the same source. When you order these from McMaster, you'll get HoloKrome brand screws (the first link).
