Not at all. Robertson screws come in all of the same lengths, shapes and sizes as Phillips screws. The only difference is the type of screwdriver that's used to screw them in; i.e. Phillips has the 'X' head (prone to slipping and threading and requires much more effort to screw them in), while Robertson has the square head (which doesn't slip, rarely threads, requires far less effort, and can be used at any angle without the screw slipping off the screwdriver).
