No,evidently they are not important because they are not supplied with the mobo,they sometimes come with a new case though.I never use them and have had 0 problems.the screw and standoffs do not touch anything that can short anyway and for thier use to be effective,you would have to use one on each side of the mobo and even then the screws side may contact the board,so what is the point.Just don't over tighten the screws and you will be fine😀
