For graphite and 60/40 Vespel/graphite ferrules, we have found that the additional torque gained using a finger-tight column nut fitting allows most users to pre-seat ferrules onto the column without using a wrench. But, for 85/15 Vespel/graphite ferrules, a wrench may still be required. Using finger-tight fittings reduces the time and effort needed for column installation and decreases the chance of overtightening the fitting.
