Locking Nut - M8 flanged nut with a nylon insert.

The nylon collar deforms around the bolt thread as the nut is tightened, gripping it so the joint resists loosening under vibration and suspension movement. The integral flange spreads the clamp load across the mounting face, so a separate washer is not required.

Used on damper and suspension mountings and on general chassis fixings.

A nylon-insert nut is intended for single use - renew it rather than refitting the original, as the locking effect is reduced once the nut has been run off the thread.

Frequently asked questions

What is the FX108046 locking nut used for?
The FX108046 is an M8 flanged nyloc nut used on damper and suspension mountings and general chassis fixings. The nylon insert grips the bolt thread against vibration and loosening, and the integral flange spreads the clamp load so no separate washer is needed.
Can the FX108046 nut be reused, or does it need replacing every time?
No, it's designed for single use, replace it every time it's removed. The locking effect of the nylon insert is reduced once the nut has been run off the thread, so refitting a used one on damper or suspension mountings risks it loosening under load.
Are the NH605041L and WM600051L the same as the FX108046?
Yes, NH605041L and WM600051L are cross-reference numbers for the same M8 flanged nyloc nut. They're interchangeable with the FX108046 for damper, suspension and chassis fixings.
