M2 Self-locking Aluminium Nuts

Self-locking aluminium nuts M2: less weight, same grip

When every tenth counts —whether on the track or in the assembly bench— the small details make the difference. These self-locking aluminium nuts for M2 threads allow for securing screws with the same reliability as a conventional steel nut, but with a significant weight reduction thanks to the material they are made from. Ideal for both slot car preparations and static model assemblies, figures, or dioramas where weight control and finish are priorities.

Main features

• Material: aluminium, lightweight and corrosion-resistant.
• Thread: M2, suitable for metric 2 screws.
• Self-locking function: prevents loosening due to vibration, without the need for a lock nut or additional adhesive.
• Pack contents: 4 units per pack (ref. AV20931).
• Finish: elegant and clean, in line with high-level preparations.

Function and performance

The self-locking system incorporated in the nut ensures that the tightening remains stable even under continuous vibration conditions, something common in slot car chassis during a race. Unlike steel nuts, the aluminium version reduces the weight of the assembly without sacrificing the security of the mounting. For demanding tuners, this type of detail makes a difference in chassis where the minimum possible weight is sought.

Compatibility and assembly

These nuts are compatible with any M2 metric screw, the most common size in 1:32 and 1:24 scale slot car chassis and components, as well as in static modelling applications. Their use is straightforward: they are hand-tightened until contact is made and then tightened with the appropriate tool to the desired torque. The self-locking insert ensures that they do not loosen over time or with use.

Ideal for…

• Slot car tuners looking to reduce the total weight of the chassis.
• Static modelling enthusiasts, figures, and dioramas needing reliable and aesthetic fasteners.
• Any assembly using M2 screws where the lightness of the assembly is valued.

Considerations

Being made of aluminium, these nuts offer lower mechanical resistance than steel in very high load applications. For joints subjected to extreme forces, it is advisable to evaluate the specific application. In the usual context of slot and modelling, their performance is more than sufficient and the weight advantage more than compensates.

Frequently asked questions

How many nuts are included in the pack?

The AV20931 pack includes 4 self-locking aluminium nuts M2.

What thread are these nuts compatible with?

They are specific for M2 metric screws, the most commonly used standard size in 1:32 and 1:24 scale slot car chassis and components.

Why choose aluminium instead of steel?

Aluminium significantly reduces the weight of the assembly compared to steel. In slot preparations where the minimum possible weight is sought, this detail can make a difference in the car's performance on the track.

Does the self-locking system require any additional adhesive?

No. The self-locking insert of the nut prevents loosening due to vibration without the need to add any adhesive or lock nut.

Can these nuts be reused?

Yes, although like any self-locking nut, the effectiveness of the insert may slightly decrease with repeated use. For permanent or competition assemblies, it is recommended to use new units.

Self-locking aluminium nuts M2 (pack of 4, ref. AV20931) — lightweight fasteners designed for slot car chassis preparation and static modelling builds at 1:32 and 1:24 scale. Aluminium construction delivers significant weight savings over steel equivalents while maintaining secure, vibration-resistant clamping. A favourite among slot car tuners and modellers looking to optimise every gram of their builds.
