Nylon Insert Locknut Heavy Thin NC: Heavy hex nut with a nylon-filled collar at its back end. When the cap-screw or bolt reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the cap-screw or bolt with it is subjected to vibration. The nylon insert comes in various colors. Has greater surface area than NM-series nuts, making wrenching easier. Designed to be used with cap-screws and bolts which have a minimum tensile strength not greater than 90,000 psi. Used in bridge and building construction, material handling, heavy equipment and oil field machinery. Steel nylon insert stop nuts are less expensive than grade-C automation lock units. Nylon insert nuts are not designed to be used at temperatures over 250 degrees Fahrenheit. *ZB - BLUE ZINC

FAQs

How does a nylon lock nut work?

Nylon lock nuts have a nylon collar inserted into a recess at the nut's top. This recess and nylon insert are slightly smaller than the outer thread diameter. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. This elasticity causes friction between the nylon collar and the screw making the connection resistant to loosening.

Which way do nylon lock nuts go?

Nylon lock nuts go nylon side away from the head of the bolt or screw. The threading should be coming out of the nylon insert side of the nut as the bolt or screw is fastened.

Are Nylock nuts reusable?

Yes, nylon insert lock nuts are reusable. However, we do not recommend frequent repurposing of the same nylon lock nuts in critical connections on a given application.

What is the purpose of a Nylock nut?

Nylock nuts are economical lock nuts for applications involving vibration or motion. The nylon insert of these locking nuts helps the assembly resist loosening under the application's vibration or motion.

How do you use lock nuts?

Most lock nuts are used the same way traditional nuts are; by simply fastening them to the opposite side of a bolt. The locking action activates after the nut is fastened down. The exception to this is castellated nuts and slotted nuts, which needs a hole drilled into the bolt and a cotter pin to finish installation.

Can lock nuts be removed?

They're not designed to be removed easily. If they were, they wouldn't be very good lock nuts! That said, it is possible to remove locknuts. It may require some patience and, in some cases, power tools to remove them. The exact method will vary based on application and lock nut.

Do you need a lock washer with a lock nut?

No, you don't need a locking washer to use a locking nut or vice versa. Most applications will call for using one or the other, not both. That's not to say you can't use both a lock nut and lock washer as part of the same assembly. It's just not common to do so; one will suffice for most jobs.
