New Surplus, Sold Per Each

A self-locking hex nut is a type of hexagonal nut that is designed to resist loosening due to vibration or movement. It typically features an integrated locking mechanism that prevents it from turning or coming undone once it has been tightened. This locking mechanism can take several forms, such as a nylon insert or a deformed metal design, that either increases friction or mechanically engages with the threads of the bolt or stud, ensuring a secure fit.
