NSR M2.5 Allen replacement tip

The M2.5 Allen tip that keeps your NSR key always ready for adjustments

When a tip wears out or gets lost, work at the preparation bench comes to a halt. This NSR M2.5 replacement Allen tip (ref. NSR4422) is specifically designed to replace or complement the original tip of the NSR key, ensuring that you can continue adjusting, assembling, and disassembling the components of your slot cars with the same precision as always.

Function and performance

The M2.5 size is one of the most commonly used in working with competition slot cars: it is involved in adjusting chassis screws, securing motors, mounts, and other preparation elements where hexagon precision is key. Having a tip in good condition prevents rounding of screw heads, a problem that can be costly when working with delicate parts.

Compatibility

This tip is designed as a replacement for the NSR Allen key. If you use NSR brand tools at your workbench, this is the correct reference to replenish the M2.5 tip. Before placing your order, check that your NSR key's clamping system accepts this type of interchangeable tip.

Assembly and preparation

The replacement is straightforward: remove the worn tip from the tip holder of your NSR key and insert the new one following the clamping system specific to the model. No additional tools are required. Once installed, ensure it is properly seated before applying torque to any screw.

Common mistakes

• Applying excessive force with a worn tip: the damaged hexagon slips and can irreversibly damage the screw head. Change the tip as soon as you notice play.
• Confusing sizes: M2.5 is not interchangeable with M2 or M3. Always check the screw size before choosing the tip.
• Not securing the fit: a poorly secured tip in the tip holder transmits less torque and increases the risk of slipping.
