XRAY NT1 spring steel engine nut by Arrowmax AM-NT1-330008  [AM-NT1-330008]

Engine nut for NT1 chassis

This Arrowmax AM-NT1-330008 engine nut is an RC-scale spring steel retention part intended for XRAY NT1 chassis use. It is a dedicated nut component that helps keep the engine assembly secure during track runs and routine maintenance, without implying any real vehicle applications.

The part is designed to work as a locking/retention element on NT1 engine mounts where compatible nuts are required. Installers typically replace a worn or damaged nut with this spring steel version to restore clamping reliability and to reduce the chance of loosening under vibration common in RC racing.

When fitting, ensure correct thread engagement and hand-tighten to seat the nut before final torque. Use proper RC tools for access and confirm compatibility with your XRAY NT1 engine mounting hardware; do not force mismatched threads.
