Looks like all the easy definitions have been taken care of by others.
More GD&T always drives the floor jockeys piping hot mad, so do that to excess. Position at MMC, angularity, flatness of the nail head, give them the beans.
However, Having also worked with enough plant floor people-
If you don't have a separate view showing the fully installed configuration you are wasting your time with all those notes. Nobody gonna read them.
There's lots more stuff you could include. For example:
indication of which part of the hammer should be used to strike the nail
recommended angle of entry for the nail to penetrate the wood
recommended angle of impact for the hammer against the head (once correct part of hammer is indicated)
scale: how long/thick is the nail? How thick/deep is the piece of wood? Is the illustration to actual scale, or is it a more general representation of the objects?
material composition of nail
type and density of wood
grain direction of wood
is the diagram indicating relative positioning, or absolute? For example, does the wood always need to be parallel to the ground, and does the nail always need to be perpendicular to the ground.
description of variances with respect to types of nail heads; some may have squared edges, others may be beveled.
Then the marketing and graphics design team gets it, and it reads "hit nail".with a graphic that may or may not show to hit the nail on the side of the nail.
