The Unifix Grade 2 UNC Nylon Insert Nuts are an essential hardware solution for professionals and DIY enthusiasts who require reliable, vibration-resistant fastening in automotive, construction, and general repair projects. These nuts are designed to stay securely in place thanks to an integrated nylon locking ring that prevents loosening over time, though they are intended for single-use applications as the nylon insert loses its locking grip once removed.

It is not recommended. The nylon insert is designed to deform to match the bolt threads, and it loses its effective locking grip upon removal.
Grade 2 refers to the hardness and strength classification of the steel, typically used for standard, general-purpose fastening needs.
The zinc plating provides rust resistance, but they are not intended for continuous submersion or high-moisture environments without additional protection.
Yes, nylon has a specific melting point. These should not be used in high-heat areas like exhaust systems or near fire sources.
No, these are UNC (Unified National Coarse) threaded nuts and are not compatible with metric threaded bolts.
Check for debris in the threads or a mismatch in the UNC thread pitch; do not force the nut as this can cross-thread the bolt.
The nylon insert may be damaged or the bolt diameter may be too small for the specific nut size; verify the specifications of both components.
To ensure maximum effectiveness, verify that your mating bolt has the exact UNC thread pitch matching the nut. Avoid using these nuts on bolts that have been stripped or damaged, as this can compromise the integrity of the nylon insert. When installing, use a calibrated wrench to tighten the nut to the required torque specification for your project. If you are dismantling a joint, be aware that the locking properties of the nylon insert are significantly reduced once removed; it is recommended to replace the nut with a new one to maintain the vibration-resistant seal. Keep the nuts in a dry environment to maintain the longevity of the Bright Zinc Plating.
