Only swagged aluminum arrrows or tapered wood arrows require glue-on nocks. Glue must be used sparingly, otherwise it can weaken the plastic. More recently even aluminum and carbon-aluminum shafts use nock bushings so that nocks are press fit without glue.
Most carbon arrows accept internal, pressure fitted nocks that do not require glue. Even so, I use the bushings for better precision nock alignment and enhanced nock end protection from robinhoods.
