M2.5x6mm screws

M2.5x6mm Screws: the small element that must not be missing from your toolbox

In the world of slot racing, great results are built on small details. The M2.5x6mm screws (ref. SICH89) are one of those elements that go unnoticed until you find yourself missing one at the least opportune moment. Having a well-organised assortment of these screws guarantees that you can undertake any assembly, adjustment, or repair without interruptions.

Function and performance

The M2.5x6mm screws are a widely used standard size in the preparation and assembly of slot car chassis, securing motor mounts, fastening internal components, and multiple anchor points where precise tightening is required without risking damage to delicate parts. Their M2.5 metric offers the right balance between strength and discretion, being robust enough to withstand the vibrations of competition and fine enough to work in tight spaces.

Compatibility and applications

This type of screw fits into numerous applications within the hobby:

• Securing motor mounts and supports in slot car chassis of various scales.
• Mounting guides and transmission components.
• Fastening bodies and body elements in competition preparations.
• Replacing lost or damaged original screws during disassembly.
• General use in static modelling projects, kits, and dioramas where this metric is required.

As it is a standard size, it is compatible with a wide variety of common adjustment tools found in the slot workshop.

Assembly and preparation

To make the most of these screws and avoid premature wear, we recommend always using the appropriate screwdriver for the screw head and not exceeding the necessary torque, especially when working on plastic or resin parts. A progressive and controlled tightening extends the lifespan of both the screw and the receiving part.

Common mistakes

• Confusing the metric: M2.5 is not the same as M2 or M3. Always check the size before forcing the screw into the housing.
• Excessive tightening: in chassis made of composite materials or high-stiffness plastic, excessive torque can create micro-cracks that compromise structural integrity.
• Not having spares: losing a screw during a preparation session can halt work. Always keeping a small stock is a recommended practice for any preparer.

Frequently asked questions

What length does this screw have and for what thickness of material is it suitable?

The length is 6 mm, making it ideal for fastening components of thin or medium thickness, common in slot car chassis and mounts. For thicker materials, a longer length may be necessary.

Is it suitable for use in club competition or only for recreational assemblies?

It is perfectly valid for both contexts. In competitive environments, standardised and precisely sized screws are, precisely, the most used by preparers to ensure repeatability in assemblies.

What type of head does this screw have?

The specific information about the type of head (hexagonal, Phillips, flat…) has not been provided by the manufacturer in reference SICH89. We recommend contacting us directly if you need this information before placing your order.

Can I use these screws in static modelling projects or dioramas?

Yes, the M2.5x6mm metric is also common in static models and diorama assemblies where discreet and durable fastenings are required.

How many units are included in the package?

The exact number of units per package is not specified in the available information for this reference. Please consult us if you need to know before completing your order.

The SICH89 M2.5x6mm screws are a must-have in any slot car preparation toolkit. Compatible with a wide range of chassis and motor mounts, these precision metric screws are ideal for slot car racing, static model kits, and diorama builds. Whether you're setting up for club competition or fine-tuning your home layout, having reliable, standardised hardware on hand ensures your builds stay solid lap after lap.

Information not available

It has not been possible to confirm with the provided information the exact type of head (hexagonal, Phillips, slotted, Torx…) or the manufacturing material of the screw (steel, stainless steel, etc.). If this data is relevant to your application, we recommend contacting us before placing your order.
