Default ? Screw head diameter?

MS24593 is a flat head machine screw with a 6-32 shank/thread. In this
application the diameter of the screwhead is important.

I went to HD and bought a 6-32 machine screw to see what length I
needed (the original having rusted beyond recognition). I compared the
HD screw with the MS and noticed it was 1/4" dia. as compared to 3/8",
so I'm wondering if I order the MS screw if the head will be large
enough.

The difference I'm seeing is caused by the 100^ angle on the MS screw,
but I don't know if the final diameter will match the original.

Would anyone with experience with the MS24593 screw please weigh in? -


I would be very curious as to what the application is for this screw.

If it is going to be any more important than holding a radio in the panel,
then you need to be thinking about the quality and strength of the screw.

HD screws have no strength guarantee, compared to a MS screw. They may have
only 10% of the strength of a MS screw. If that is the case, the head size
is the least of your worries.

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.
