A Nylock nut, is a type of lock nut designed to prevent loosening due to vibration or torque. It is equipped with a nylon collar that is permanently attached to the internal threads of the nut. The nylon collar helps maintain a secure and tight connection by resisting back-off, even in environments with vibration or movement.
Nylock nuts are commonly used in various applications, including automotive, aerospace, machinery, appliances, and more. They are particularly useful in situations where the joint may be subjected to vibration, preventing the nut from becoming loose over time.
When using Nylock nuts, it's important to ensure that the mating bolt or screw has enough thread engagement within the Nylock nut to effectively engage the nylon insert. Additionally, Nylock nuts are intended for single-use applications and may lose some locking effectiveness if reused.
