Weber # 88217 part... need to locate the 3 screws...!!

If you did remove the screws there in the fire box I WOULD put Never Seize on them. Hell there is no place I would NOT use it. As for it being too hot..............balder dash :D if it can survive the exhaust system heat of a car right up near the cat converters it will be able to handle the low temps of a grill
