That depends. Who made your cue? "Radial" is a trademarked name of a pin made by the Unlioc Corp. Some people refer to all similar pins as "radial" even though they are not the proprietary pin. If it is not a true Radial(TM) pin there is a chance it will not fit. Some cue makers use pins made to the same measurements so you'd be ok. Others are bastard pins that look the same but are slightly different.
