Precision in Every Detail: Conical Aluminium Screws for Slot Car Bodies

When it comes to securing a slot car body, small components make a big difference. The Conical Screw ø4.5mm M2.2x5mm from Scaleauto (ref. SC-5148A) is specifically designed for body assembly, providing a clean, secure, and repeatable fit every time the car is assembled or disassembled.

Technical Specifications

Function and Performance

The conical profile of the head allows the screw to sit naturally on the body, distributing clamping pressure evenly and preventing marks or deformation in the plastic. Being semi-threaded, the smooth shank facilitates centring and correct alignment before the thread engages, which is particularly practical in competition sessions where preparation time is critical.

Aluminium as a material provides an ideal combination for this type of component: low weight that adds minimal mass to the assembly and sufficient strength to withstand repeated cycles of assembly and disassembly without premature thread deterioration.

Compatibility and Applications

This screw is designed for use in slot car bodies, in applications where discreet and low-profile fastening is required due to the conical head. Its M2.2 metric is the standard specification used by Scaleauto in its own chassis and bodies, allowing for direct fit in the designed housings.

For builders working with delicate materials or custom resin bodies, the conical profile mitigates the risk of chipping or stress concentration that can occur with flat or cylindrical head screws.

Assembly and Preparation

Before threading, ensure that the housing is clean and free of debris from previous materials. Being semi-threaded, the initial insertion is straightforward: the shank guides the screw until the thread makes contact. It is advisable not to overtighten, especially on plastic or resin, as the conical geometry already provides a firm anchor with moderate torque.

For frequent disassemblies on track, a minimal application of mounting grease on the thread will extend the lifespan of both the screw and the housing.

Frequently Asked Questions

What type of bodies is this screw suitable for?

It is suitable for slot car bodies in general, being especially appropriate for those with standard conical housings of metric M2.2, such as those used by Scaleauto in its own models.

Why choose a conical screw over a flat head screw?

The conical head sits naturally in the housing, without protruding from the plane of the body, which enhances aesthetics and avoids aerodynamic interference. Additionally, it distributes clamping pressure better over the material.

Is aluminium strong enough for competitive use?

Yes. In small format components like this screw, aluminium provides the necessary strength for the usual cycles of assembly and disassembly in club or competition, with the added advantage of its low weight.

How many units does the product include?

The available information does not specify the number of units per blister or bag. We recommend checking the product sheet or contacting us to confirm before placing your order.

Is it compatible with chassis from other brands?

Compatibility depends on the housing of the receiving chassis. As it is M2.2 metric, it will work in any chassis or body that uses this thread standard, regardless of the brand, as long as the housing diameter and depth are in accordance with the specified dimensions.

The Scaleauto SC-5148A is a conical aluminium screw M2.2x5mm with a ø4.5mm head, designed for slot car body mounting. Its semi-threaded profile ensures precise alignment and secure fastening with minimal weight impact — an essential small part for slot car preparation, club racing, and competition tuning.
