ISO7040 Self Locking Nut With Nylon Insert Stainless Steel 304 Prevailing Torque Nuts

ISO7040 Prevailing torque nuts with nylon ring insert

Product Description:

Nylon insert locknuts are produced by forming and tapping nuts that include a tubular feature on top that receives a nylon ring.

The tubular top is crimped to capture and hold the ring from spinning while the mating part self threads into the nylon during assembly.

The nylon ring size and crimping process to secure the ring must be controlled to tight tolerances.

The nylon insert grips the bolt to resist loosening without damaging threads.

They're reusable, but their holding power lessens with each use.

Applications:

The Full Hex ISO 7040 locknut is commonly used in many general purpose applications.

Produced in high volumes, the smaller diameter products are relatively inexpensive.

As compared to All-Metal Locknuts, Nylon Insert Locknuts are less damaging to mating threads, but have heat limitations and the nylon develops memory and prevailing torque erodes.
