No

You already explain why: they only ask for undergraduate details. The graduate school admission committees already have too many applications to look at. Don’t over-load them

Your idea is actually counter-productive. If your high school record is better than your undergrad credentials, they would wonder why your academic achievement is regressing instead of progressing.

Should I include high school details in Grad School Resume?
I am trying to install a front wheel in a bike - the axle of the wheel is threaded, but I have trouble finding out what size thread it is, and what nut can go on this. The size of the thread on the axle is the same as of a 8 mm screw, but a standard M8 nut (with 13 mm hex) does not fit on it. Do bikes have some special kind of nut there?

If I look at the thread, and at a standard M8 screw, the thread on the bike axle is a bit more dense then on the screw, but I am not aware of existence of two kinds of M8 nuts, so far every M8 nut did fit every M8 screw.
