M2x2 Allen Screw

The right screw for every adjustment in wheels and crown gears

In the world of slot racing, the small components are what hold everything else together. The Scaleauto M2x2 Allen Screw (ref. SC-5109) is a precision accessory specifically designed for the fixation of wheels and crown gears, where proper fastening is crucial for stable and consistent performance on track.

Function and performance

This M2 metric Allen screw with a length of 2 mm fits precisely into the applications for which it has been designed. Its Allen head allows for the application of the correct torque without the risk of damage, which is fundamental when working with small components such as wheels or crown gears in competitive or prepared slot cars.

• Metric: M2
• Length: 2 mm
• Application: fixation of wheels and crown gears
• Brand: Scaleauto
• Reference: SC-5109

Compatibility and assembly

As a specific component from Scaleauto, it naturally fits with the axles, wheels, and crown gears in the brand's catalogue. If you are preparing or maintaining a Scaleauto car, using the original screws ensures a fit without play or improvisation.

For tightening, use an Allen key of the appropriate size for the M2 head. Excessive tightening can damage both the screw and the receiving component, so apply just enough force to secure the piece without stressing the material.

Common mistakes

One of the most common errors in the slot workshop is replacing this type of screw with others of similar but not identical measurements. A screw with incorrect length or metric may not anchor the wheel or crown gear properly, causing vibrations, loss of concentricity, or even loosening during a race. Always using the correct reference is the simplest way to avoid these problems.
