Query: Gutter screws to replace nails

I installed 30 with a power screwdriver with great success. They replace spikes with and without spirals. Only issue was the torx bit tended to slip in the torx head of the screw.My old spikes were so loose that some could be removed with the fingers. Installing new screws at every other location seemed to work OK except at the corners of the house where the downspout added extra load. Also, hanging christmas lights on the gutter has paid the price on my old spikes so these screws help a lot.
