I hope you are not using hardware store screws in your homebuilt for any
important functions. You are gambling your life. You could be a _big_
looser.


No, no, no, no

We do not use hardware from Home Depot Aerospace for anything except
non-structural things like holding the floorboards in place.

I mentioned HD and the cml screw because I thought the cml screw would
have the same profile as the MS screw and I could use it as a model of
what to purchase. What I didn't realize is that the underside angle of
the head (countersink) for the MS screw was different from the cml
screw, so that was a good idea gone bad.

Still don't know if a #6 MS24694 is going to give me a 3/8" dia head.

Head diameter, 0.3765 to 0.3813. Google is your friend,

There are several head angles common, 82, 90, 100, and 118 which I've
used in various applications for various reasons.
