These are compatible parts and do not fit all the models of the brands mentioned. We are unable to advise you if these spool pins will fit your machine as there are so many makes and models of sewing machines and this is why we have added the dimensions to the photo so that you can make your own choice. If the hole in your machine is smaller than the size of the spool pin dimensions, you can take a sharp blade and carefully trim one of the tabs on the spool pin to fit.
