XRAY NT1 Locking Engine Nut Spring Steel - AM-NT1-330008 by Arrowmax  [AM-NT1-330008]

Engine lock nut for NT1

The Arrowmax AM-NT1-330008 is a spring steel engine nut engineered for XRAY NT1 chassis mounting points in RC models. It is supplied as an aftermarket retention nut intended to keep the motor assembly secure during competitive runs and during routine maintenance, without suggesting any full scale vehicle use.

This nut serves as the locking element on NT1 engine mounts when a spring steel replacement is required. Model builders commonly swap out damaged or stretched nuts for this part to recover clamp strength and reduce the chance of loosening under the vibration typical of racing.

Fit the nut by ensuring proper thread alignment and hand-tightening to seat it before final tightening. Use the correct RC spanners for access and confirm the nut matches your XRAY NT1 mount threads; do not force ill-fitting threads.
