Jet nut

A jet nut,¹ also known as a k-nut,¹²³ is a special type of hex locknut that is commonly used in the aerospace and automotive racing industries.³

It has a flange on one end of the nut, the hex is smaller than a standard sized hex nut, and it is shorter than a standard hex nut. It achieves its locking action by using an elliptical offset on the un-flanged end of the nut.⁴
