The screw that fine-tunes your axle adjustment with real precision
The SC-5111 is the M2x6 mm Allen screw from Scaleauto, an essential spare component for those who take the setup of their slot cars seriously. Its main function is the regulation of axle height, one of the most sensitive adjustments in the preparation of a competition car: a few tenths of a millimetre up or down in the position of the rear axle can completely change the car's behaviour in corners.
Function and performance
This screw acts as a fastening and adjustment element in the chassis or axle support systems where Scaleauto allows for varying the height of the power unit relative to the chassis. Thanks to its M2 metric and 6 mm length, it fits precisely into the designated adjustment points, allowing for controlled adjustment without unwanted play.
- Metric: M2
- Length: 6 mm
- Head: Allen (internal hex key)
- Function: Axle height regulation
- Manufacturer: Scaleauto
Compatibility and installation
This screw is designed for use with Scaleauto chassis and supports that incorporate a height adjustment system. If you are working with chassis kits from the brand or have assembled an adjustable support set, the SC-5111 is the original replacement to maintain or replace the stock screws without compromising the adjustment.
For tightening, use an Allen key of the appropriate size for the M2 head. Excessive tightening can damage the thread in technical plastic or lightweight aluminium components; adjust firmly but without forcing.
Common mistakes
- Replacing with screws of similar but not identical measurements: even a difference of 0.5 mm in length can prevent proper adjustment or cause the screw not to tension correctly.
- Over-tightening without using a precision screwdriver or calibrated Allen key, which can deteriorate the hexagonal seat of the head.
- Overlooking that a damaged screw directly affects the repeatability of the setup: if the thread is damaged, the height point becomes unstable during the race.
Ideal for…
Club racers or builders working with Scaleauto chassis and supports who need original spare screws. Having several SC-5111 in the workshop case is a common practice among the most meticulous builders: they are small parts, easy to lose and difficult to improvise with generic screws when an exact metric is needed.
Frequently asked questions
What exactly is the purpose of axle height regulation?
Adjusting the height of the rear axle relative to the chassis allows for modifying the weight transfer of the car, the working angle of the guide, and the pressure on the braids. It is an adjustment that directly influences traction and stability in corners.
Is this screw compatible with other chassis from brands other than Scaleauto?
The M2x6 metric is standard, so it can fit any point that requires that exact size. However, it is designed and validated for the support and adjustment systems of Scaleauto. For other brands, consult the specific screws from each manufacturer.
Is it sold individually or in packs?
According to the reference SC-5111 as offered by Scaleauto, it is a single screw. Check the store listing to confirm the exact quantity in the package.
What Allen key do I need for this screw?
As it has an M2 Allen head, you will need a hex key of 1.5 mm, which is the standard size for screws of this metric. We recommend using quality precision keys to avoid damaging the head.
