Choosing nut protection

Nut protection is a cap that covers the nut and keeps dirt and moisture off it. Two figures decide which cap you need: the opening width, which has to match the width across the flats of the nut, and the thread size the nut runs on. Go by the nut you have rather than by the cap fitted now, and replace caps that no longer sit tight.
