Plain nuts usually fix in place with spring or shakeproof washers. There are however some special nut types designed to more securely lock in place. Thin nuts may be used if space is available for a second nut to lock the primary fixing nut. Self-locking ‘stiff nut’ types include the Nyloc (with nylon insert, the most common stiff nut, not for high temperatures), Aerotight and Philidas (all metal, with a deformed, split outer thread portion and higher temperature enduring) and Cleveloc (all metal, with a deformed, squashed outer thread portion). Slotted nuts are secured with a split pin. Note that a few sizes of nut use different spanner sizes to their equivalent bolt or set screw.
