Eli5 Why is there not a universal “best screw”

235 views

Why can’t we just figure out what screw -head- shape is the best and always use that. It seems pointless to have hundreds of different screw types for very similar things. Obviously this is excluding things like lug nuts or anything heavy duty.

Edit:specifying screw heads, not the threads or shape.
