I need a longer screw to replace this.
It would be helpful to know the diameter and thread count
Thank you for your question on the model 655 exhaust fan/heater/light. If the 655 is installed properly, the grille stud should be long enough. The bottom of the unit housing needs to be flush with the finished side (room side) of the ceiling dry wall. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.
