M2 x 2mm steel Allen screws (10 units)

M2 x 2 mm Allen Screws in Steel: The Reliable Fixing for Your Transmission Parts in 1/32 Slot Racing

When it comes to screws for competitive slot racing, detail matters just as much as in any other part of the car. A screw that is over-tightened, vibrates, or gives way mid-race can ruin an entire session. These M2 x 2 mm Allen screws made from high-strength steel are designed precisely to avoid that scenario: precise, repeatable, and durable fixing with every adjustment.

Function and Performance

Their main function is to secure wheels, crowns, and pinions to the rear axle of 2.38 mm (3/32"), the most widely used standard in 1/32 scale. The M2 metric and 2 mm length fit precisely into the housings of the leading transmission parts on the market, ensuring uniform tightening without lateral play.

The hardened steel they are made from provides two key advantages over lower quality options: the thread does not deteriorate with the tightening and loosening cycles typical of preparation work, and the hexagonal socket maintains its geometry intact even after many uses with the Allen key. This is especially relevant when making fine adjustments to gear ratios or quick changes between heats.

Compatibility

The M2 x 2 mm dimensions are compatible with a wide variety of wheels and transmission parts from the most common brands in the 1/32 spare parts category. Being a standard format, they fit into the screw housings present in crowns, pinions, and wheel hubs designed for 3/32" axles.

Assembly and Preparation

For proper tightening, it is recommended to use the appropriate Allen key for the internal hexagon of the M2 screw and apply a moderate torque: the hardened steel offers sufficient strength, but the M2 thread has a reduced diameter that penalises excessive tightening. In competitive applications where the car experiences continuous vibrations, it is advisable to periodically check that the screws maintain the established torque.

The pack of 10 units allows you to have spares on the workbench without relying on finding a loose part at the least opportune moment, something that any experienced preparer knows inevitably happens.

Common Mistakes

• Using a screw of incorrect length: an overly long screw can interfere with the axle or fail to make effective contact with the part to be secured. The 2 mm of this model are calibrated for the typical thicknesses of 1/32 hubs and crowns.
• Tightening dry on aluminium: if the receiving part is aluminium, excessive tightening can damage the internal thread. Applying a small amount of low-strength thread locker helps maintain torque without the need for excessive tightening.
• Confusing M2 with other close calibres: M2 is not interchangeable with M1.7 or M2.5. Before mounting, verify that the housing corresponds exactly to the M2 metric.

Frequently Asked Questions

What type of axle are these screws designed for?

They are designed to secure parts onto 2.38 mm (3/32") axles, the most common diameter in 1/32 scale competitive and advanced hobby slot cars.

How many units does the pack include?

The pack contains 10 Allen screws M2 x 2 mm, allowing for a good stock in the preparation case without needing to resort to loose units.

What Allen key do I need to tighten them?

You will need an Allen key compatible with the internal hexagonal head of the M2 screw. Check the manufacturer's specifications or your set of keys to identify the exact size of the internal hexagon.

Can they be reused multiple times?

Yes. Being made from high-strength steel, the hexagonal socket and thread withstand multiple cycles of tightening and loosening without deforming, provided the correct tool is used and the recommended torque for the M2 metric is not exceeded.

Are they compatible with aluminium and plastic wheels?

Yes, as long as the screw housing is machined to M2 metric. For aluminium wheels, it is advisable to use low-strength thread locker to protect the material and ensure tightening without damaging the internal thread.

Can they also be used to secure crowns and pinions?

Yes. Any transmission part with an M2 housing for Allen screws — crowns, pinions, or wheel hubs — can be secured with these screws, as long as the 2 mm length fits the thickness of the housing.
