M2 Allen key

The tool that should not be missing from any slot preparation bench

When working with competition slot cars, every screw counts. Insufficient tightening can misalign the chassis or loosen a component during a race; excessive tightening can damage the thread of a delicate part. The NSR M2 Allen key (ref. NSR4411) is designed to provide exactly the control you need on M2 screws, the most common size in motors, axles, chassis, and bodies of 1/32 scale slot cars.

Function and performance

M2 screws are present at virtually all critical points of a well-prepared slot car: motor mounting, chassis adjustment, body securing, or chassis component assembly. Having the specific key for this size prevents damaging the screw head, which is especially important when working with precision parts that are frequently disassembled and reassembled during preparation and tuning.

Compatibility

Suitable for any Allen (internal hex) screw of M2 metric, regardless of the car or component brand. Particularly useful for NSR cars and spare parts, although its application extends to any assembly that uses this type of screw.

Assembly and preparation

Its use is straightforward: it fits precisely into the head of the M2 screw and allows both tightening and loosening without the risk of slipping or damaging the internal hex. We recommend keeping it handy alongside other tuning tools on the workbench.

Ideal for…

• Preparers and enthusiasts who regularly work with competition slot cars.
• Anyone performing maintenance, tuning, or modification of slot components with M2 screws.
• Use on chassis, motors, axles, and bodies of 1/32 scale cars.

Frequently asked questions

What screws is this Allen key suitable for?

It is specifically designed for Allen (internal hex) screws of M2 metric, the standard size in much of the components of 1/32 scale slot cars.

Is it compatible with cars from other brands besides NSR?

Yes. Being a standard M2 metric tool, it is suitable for any screw of that size, regardless of the car or component manufacturer.

Why use a specific key instead of a generic set?

Specific tools for slot racing usually have a finish and tolerances that are tighter than generic hardware store keys, which reduces the risk of damaging the screw head on small and precision parts.

How often is this tool used in slot maintenance?

Very frequently. M2 screws appear at virtually all adjustment points of a slot car: motor, chassis, body, and chassis. It is one of the most used keys on the preparation bench.

The NSR4411 Allen key M2 is an essential tool for slot car preparation and tuning. Compatible with all M2 hex screws found in 1/32 scale slot cars, it provides precise tightening and loosening without damaging screw heads. A must-have in any slot car workbench, suitable for NSR, Slot.it, Scaleauto and other leading brands' components.
