FAQs about Nyloc Nuts

What is a nylon insert nut and how does it work?

Nylon insert nuts (often called Nyloc or nylon lock nuts) have a nylon collar inside that grips the bolt threads, creating friction that resists loosening from vibration or movement.

Can nylon insert nuts be reused once removed?

Yes, but it’s not advised as the nylon insert gradually wears and the locking effectiveness diminishes with repeated use. 

Do I need a washer or spring washer with these nuts?

In most cases no as the nylon insert itself provides locking action. Washers may still be used for load distribution if your job at hand requires it.

Can I use nylon insert nuts in high-vibration applications?

Yes, the internal nylon collar grips the bolt threads, creating friction that resists loosening from vibration. This sees them used on automotive parts, and equipment where vibration is a consideration.

Are nylon insert nuts suitable for outdoor use?

Yes, these Nyloc nuts are manufactured in A2 stainless steel which offers a high resistance to corrosion, making them ideal for prolonged use in internal and external applications.
