Hello, These screws are designed for Plasterboard so have not been tested for use on end-grain, therefore we cannot guarantee its performance if used in end-grain. Generally for screwing into end grain you would use a dowel or insert nut. There may be some screws that are more suited to end grain, but you may wish to check with a competent trade person which you should use (there are other factors which need to be accounted for i.e the thickness of the plywood, weight applications etc. Thanks for using Q&A.
