M2 Self-locking Aluminium Nuts

Aluminium self-locking M2 nuts with flange: less weight, more precision in every adjustment

When every tenth of a gram matters in the preparation of a slot car, choosing the right fastening element makes all the difference. These aluminium self-locking nuts for M2 screws feature an integrated flange, eliminating the need for a washer and simplifying assembly without compromising grip.

Main features

• Material: machined aluminium, significantly lighter than equivalent steel.
• Metric: M2.
• Integrated flange: distributes the tightening load without the need for an additional washer.
• Self-locking: resists loosening due to vibration, common on track during long sessions.
• Pack contents: 4 units.

Function and performance

The main advantage of replacing steel nuts with aluminium on a competition chassis is the weight reduction in areas where the strength of steel is not required. In the context of slot racing, where M2 screws frequently appear in the fastening of motor pods, guides, bodies, or electronics, accumulating small weight savings at each anchor point contributes to a lighter and more balanced overall result.

The self-locking system prevents the nut from loosening due to the vibrations inherent in track circulation, something that can occur with conventional nuts during long sessions or on rough-surfaced circuits. The flange, in turn, better distributes the tightening pressure over the surface, protecting more delicate materials such as plastics or resins.

Assembly and preparation

Assembly is straightforward: by incorporating the flange, there is no need to add a separate washer, which reduces the number of parts in play and speeds up both assembly and disassembly during tuning. We recommend tightening with the appropriate wrench to the correct torque: aluminium, while robust for this application, does not tolerate the same tightening as steel, so it is advisable not to overdo it.

Compatibility and applications

Suitable for any standard M2 screw. Its most common uses in the slot hobby include:

• Fastening motor pods in resin or plastic chassis.
• Anchoring bodies where weight reduction is sought in the upper part of the car.
• Securing guides and electronic components in competition setups.
• Applications in static modelling and dioramas where lightweight and play-free fastening is required.

Considerations

Being made of aluminium, these nuts are not intended for points that require extreme tightening or are subjected to high shear forces. For those positions, steel remains the more conservative choice. In the rest of the common applications in slot racing and modelling, aluminium offers a very favourable strength-to-weight ratio.

Frequently asked questions

Are they suitable for all M2 screws on the market?

Yes, they are compatible with any standard pitch M2 screw, regardless of the brand or material of the screw.

How many units are included in the pack?

The pack contains 4 nuts.

Why do they have an integrated flange?

The flange serves the function of a washer: it distributes the tightening pressure over a larger surface, protects the material it rests on, and prevents the nut from sinking into soft surfaces. By being integrated, it simplifies assembly and reduces the number of loose parts on the workbench.

Can they be reused multiple times?

The self-locking nuts can be reused, although the locking element (usually a nylon insert or a deformation in the metal itself) may lose some effectiveness with repeated tightening and loosening cycles. For competition use, it is advisable to periodically check them and replace them if any play in the locking is observed.

What is the difference between these nuts and equivalent steel ones?

The main difference is weight: aluminium is considerably lighter than steel. In terms of strength for the common applications in slot racing and modelling, aluminium is more than sufficient. Steel would still be preferable in points of very high stress.

Aluminium self-locking M2 nuts with integrated flange, pack of 4 units. Lightweight and corrosion-resistant, these nuts are ideal for slot car preparation, model building and competition-level assembly where every gram counts. Compatible with all standard M2 screws. No washer needed thanks to the built-in flange. Perfect for slot car chassis, motor pods, guide mounting and bodywork fixings.
