Function and performance

The conical profile of the head allows the screw to sit flush with the surface of the body, avoiding unnecessary protrusions and providing a stable fixing without damaging the finish. Being semi-threaded, the smooth shank area acts as a centring guide, facilitating repeated assembly and disassembly without degrading the housing.

Aluminium is the ideal material for this type of fastener in slot: it reduces weight compared to steel, does not corrode, and maintains very tight dimensional tolerances, essential when working with resin, lexan, or thin polycarbonate bodies.

Assembly and preparation

For correct assembly, the housing in the body must be well executed with a drill or conical countersink according to the geometry of the head. A well-prepared hole ensures that the screw seats completely and that the body is not under tension or misaligned. It is recommended not to overtighten: aluminium is lightweight but has a limited torque compared to steel, and forcing it can damage the thread.

Who is this screw for?

It is aimed at both the club preparer seeking precision in every detail of the assembly and the competition driver needing confidence in the fixing of their body during the most demanding sessions. It is also useful for the enthusiast working with Scaleauto construction kits who wants to maintain the authenticity of the components.

Frequently asked questions

How many screws are included in the package?

The available information does not specify the quantity per unit of sale. We recommend checking the store listing or contacting us to confirm before placing your order.

Is it compatible with bodies from other manufacturers?

As long as the housing in the body is compatible with the M2.2 metric and the conical geometry of the head ø4.5mm, it can be used on bodies from different manufacturers. However, it is designed and marketed by Scaleauto for its own body system.

Can I use it on lexan or polycarbonate bodies?

Yes, as long as the hole is properly countersunk. In fine materials like lexan, it is especially important not to overtighten to avoid deformation.

Does aluminium withstand repeated use?

Aluminium is sufficiently durable for the usual cycles of assembly and disassembly in the maintenance of a slot car. If very frequent changes are made, it is advisable to periodically check the condition of the thread to ensure there is no play.

The Scaleauto SC-5148G is a conical semi-threaded aluminium screw specifically designed for slot car body mounting. With an M2.2 thread, ø4.5mm head diameter and 11mm shank length (12.3mm total), it delivers precise, lightweight fixing for resin, lexan and polycarbonate bodies. An essential detail for slot car builders and club racers looking for reliable, clean body fitment.
