NSR M2 Allen replacement tip

Replacement Allen M2 Tip for the NSR Key: Simple, Precise, and Essential in Any Slot Workshop

When working on the setup of our slot cars, Allen tips are often overlooked until they wear out or get lost. NSR knows this, which is why they offer this specific M2 replacement tip for their key, allowing us to keep the tool operational without resorting to makeshift solutions that could damage the chassis screws.

Function and Performance

The Allen M2 tip is one of the most commonly used sizes in the assembly and preparation of competition slot cars. It is involved in the tightening and loosening of chassis screws, motor mounts, and other small components that require precision. Having a tip in good condition makes the difference between a clean adjustment and a damaged screw that complicates future interventions.

Compatibility

This tip is designed as a direct replacement for the NSR Allen key. If you use NSR tools in your workshop, this is the correct spare part. If you have any doubts about compatibility with other keys from the same brand, check the reference of your original tool.

Assembly and Preparation

Changing the tip on NSR keys is a quick process and does not require additional tools. Replace the worn tip, and the key is ready to continue working with the same precision as on the first day.

Common Mistakes

• Using a worn tip: causes rounding of the screw heads, making future maintenance operations difficult.
• Forcing with the wrong size: an M2 tip should only be used on M2 Allen screws. Using an inappropriate size can damage both the tip and the screw.
• Not having spares: during a setup session, running out of an operational tip is one of those easily avoidable setbacks with a spare in the drawer.
