Bolt printing idea

I was thinking about printing threaded bolts as found two issues:
1, printing it standing will take much more time than layed down
2, if I lay it down then support will be needed, which ruins the thread
3, in standing position the layers wouldn't strengthen the structure, at bigger force the layers can easily split.

So to solve these problems, I two flat surfaces to the thread so this way it can be layed down, this way it can be printed quicker and layers will give more strength to the threads.
