A '''distorted thread locknut''',<ref name="McMaster3139">McMaster, p. [http://www.mcmaster.com/#catalog/114/3139 3139].</ref> is a type of [[locknut]] that uses a deformed section of [[screw thread|thread]] to keep the [[nut (hardware)|nut]] from loosening from vibrations or rotation of the clamped item. They are broken down into four types: '''elliptical offset nuts''', '''centerlock nuts''', '''toplock nuts''' and '''partially depitched (Philidas) nuts'''.

==High temperature use==

Because these nuts are solid metal, they are effective in elevated temperature settings, unlike [[nyloc nut]]s. High [[Bolted joint#Property class|grade]] nuts are good up to {{convert|1400|F|C|abbr=on}}. High strength distorted thread nuts cannot be used with low strength fasteners because the hard nut will act like a [[tap and die|die]] and destroy the threads on the fastener.<ref name="smith"/>
