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

Retention nut for NT1 mounts

The Arrowmax AM-NT1-330008 spring steel engine nut is an RC-scale retention item engineered for XRAY NT1 chassis engine mount applications. This dedicated nut helps hold the engine assembly steady during track sessions and workshop servicing, without suggesting any application to full size vehicles.

Designed to act as a locking retention part on NT1 engine mounts, the nut is typically used to replace damaged or fatigued factory nuts to restore clamping performance and reduce the chance of loosening from race vibration.

When fitting the nut, check that threads engage correctly and hand-tighten initially to seat the part before applying the final torque. Use the correct RC tools and confirm the nut matches your XRAY NT1 mounting threads; do not force mismatched fasteners.
