M2 x 5mm steel Allen screws (10 units)

M2 x 5 mm Allen screws in hardened steel for when every millimetre of threading counts

In the preparation of 1/32 scale slot cars, the details of assembly make the difference between a chassis that remains firm throughout the session and one that starts to give way in the first corners. These Allen screws M2 x 5 mm in hardened steel respond to a specific need: to provide a deeper fastening where the standard shorter thread does not work with sufficient grip.

Function and performance

The M2 metric is the most common in precision fasteners for 1/32 scale slot chassis, and the length of 5 mm is particularly useful in situations where the material to be fastened has a greater thickness than usual. Some practical examples include:

• Fixing reinforced motor mounts or special 3D-printed brackets.
• Mounting ballast in areas of the chassis with a higher accumulation of material.
• Replacing screws that have lost grip due to wear, when depth needs to be gained.
• Limiting the travel of the front axle in applications where geometry demands it.

Hardened steel allows for a firm torque application without deforming the hexagonal imprint, resulting in adjustments that do not loosen between sessions. At the same time, the material offers adequate wear resistance due to repeated use, common in preparation environments where screws are frequently mounted and dismounted.

Compatibility and assembly

As these are standard metric M2 screws, they are compatible with any M2 thread present in commercial or custom-machined chassis. The Allen head (metric hexagonal) requires the corresponding Allen key for size M2, a common tool in any slot preparation kit. It is recommended not to over-tighten on soft materials such as resins or 3D printing plastics, to preserve the thread of the chassis.

Common mistakes

• Using M2 x 5 mm screws where M2 x 3 mm are needed: if the screw protrudes from the other side of the mount, it may interfere with moving parts of the chassis. Always check the available space before mounting.
• Tightening without prior guidance: on new threads in plastic or resin, starting the threading by hand before using the key reduces the risk of cross-threading.
• Not having spares: having a pack of 10 units prevents halting a preparation session due to the loss or wear of a screw.

Frequently asked questions

What is the difference between an M2 x 5 mm screw and an M2 x 3 mm screw?

The metric (M2) is the same in both cases; what changes is the useful length of the thread. The 5 mm screw penetrates 2 mm deeper into the material, resulting in greater grip on mounts or parts with more thickness. For applications in standard chassis of low thickness, the 3 mm screw is usually sufficient; for reinforced mounts or thick ballast, the 5 mm offers more security.

Do I need any special tools to mount them?

Only an Allen key of the appropriate size for M2 thread. It is a basic tool in any slot preparation kit. If you do not have one, you will find them in our tools section.

Are they compatible with 3D-printed chassis?

Yes, as long as the chassis has machined M2 threads or M2 metal inserts. In chassis printed directly in plastic without inserts, it is advisable to start the thread carefully and not to over-tighten to avoid damaging the thread of the material.

Why does the pack include 10 units?

In slot preparation, it is common to frequently mount and dismount screws. Over time, the hexagonal imprint may wear out or the thread may deteriorate. Having spare units prevents interrupting an adjustment session due to the lack of such a small but critical component.

Can they be used with any Allen key on the market?

Yes. As they are standard M2 screws with a conventional Allen head, they are compatible with any general-use M2 Allen key.

M2 x 5mm Allen screws in hardened steel for 1/32 slot car chassis. Ideal for reinforced motor mounts, 3D-printed brackets and custom ballast fixing. Pack of 10 units ensures you always have a spare on hand during technical preparation sessions. Standard M2 metric thread, compatible with all M2-threaded slot chassis components. Ref. T839011.
