Description
Resists Loosening: 1/4″-20 Zinc Plated Nylon Lock Nuts
This is a 1/4″-20 Nylon Lock Nut, designed specifically to resist loosening caused by vibration and torque. Its key feature is the integrated nylon insert at the top, which creates friction against the bolt threads. Installation requires a standard 7/16″ wrench or socket.
Manufactured from Grade 2 steel, this nylon locking nut offers standard strength suitable for general-purpose fastening. It features an Electro Galvanized zinc plated finish, providing moderate corrosion resistance for indoor or dry applications.

FAQ
How does the nylon insert prevent loosening?
As the bolt threads into the nylon lock nut, it deforms the nylon ring inside. This creates strong friction (prevailing torque) against the threads, making the nut significantly resistant to vibrating or backing off.
Can nylon lock nuts be reused?
For critical applications where the locking feature is essential for safety or function, it’s recommended to use a new nylon lock nut each time. Reuse significantly reduces the locking effectiveness as the nylon wears.
What is the zinc plating for?
The electro-galvanized zinc plating provides a protective layer over the steel, offering moderate resistance to rust and corrosion, mainly for indoor or dry environments.
What tool is needed for this 1/4-20 nylon lock nut?
You need a standard 7/16 inch wrench or socket.
