M2.5 x 2mm Allen screw (10 units)

Precision screws for those who leave nothing to chance on the track

In the 1/32 spare parts category, the small details make the difference between a car that withstands session after session and one that loses adjustment in the first fast corner. These Allen screws M2.5 x 2 mm from the T800 line are designed precisely for that type of enthusiast: the one who inspects, adjusts, and prepares their vehicle with the same rigor as a competition mechanic.

Function and performance

With a metric of M2.5 and a length of 2 mm, these screws offer a very low profile that makes them ideal for areas where the available space is minimal. The hexagonal head for Allen key allows for the application of the correct torque without deforming either the tool or the housing, which is especially important when working with transmission parts, axles, or chassis components that need to be disassembled regularly.

The hardened steel ensures that the screw does not yield or deform under the constant vibrations of the track, keeping the mechanics firm even on technical circuits with a lot of rhythm changes.

Technical specifications

• Metric: M2.5
• Length: 2 mm
• Head type: Allen (internal hexagonal)
• Material: Hardened steel
• Contents: 10 units
• Reference: T839008

Assembly and preparation

For installation, use an Allen key of the appropriate size for the M2.5 head and apply the torque progressively. On delicate parts such as crowns or wheels, avoid exceeding the necessary torque: the length of 2 mm leaves little thread margin, so excessive force can damage the housing. If working with threaded parts made of aluminium or technical plastic, a slight application of low-strength thread lock may help prevent the screw from loosening due to vibration without hindering future disassembly.

Common mistakes

The most common mistake with screws of this metric is confusing them with M3, which has a slightly larger diameter. Always check that the metric matches before forcing the entry into the housing. It is also common to use a worn Allen key that slips and ends up stripping the head: with precision screws, having the tool in good condition is not optional.

Who is this spare part for?

It is designed for both preparers who need stock of standard screws and enthusiasts who simply want to have spares on hand before a workshop night turns into a frustrating search. Coming in a pack of 10 units, it covers the maintenance of several vehicles or allows for replenishing screws worn out from continuous track use without running short.

Frequently asked questions

What Allen key do I need for these M2.5 screws?

The M2.5 screws with internal hexagonal heads typically use an Allen key of 1.5 mm or 2 mm depending on the manufacturer. Check the specifications of your tool or try both sizes before tightening to avoid damaging the head.

Are they suitable for transmission parts like crowns or pinions?

Yes. Their low profile of 2 mm in length and metric M2.5 makes them compatible with many fastening points in transmission, wheels, and centring components of 1/32 slot cars, as long as the original housing is designed for this metric.

Can I use them in plastic chassis or only in metal?

They can be used in threaded housings made of technical plastic, although in that case, it is advisable to be especially careful with the torque to avoid damaging the thread. In metal housings, they offer greater durability and better tolerate repeated cycles of assembly and disassembly.

How often should I check and replace these screws?

With regular use in competition or club track, it is advisable to check the condition of the head and thread after several intense sessions. If the head shows signs of deformation or the thread does not grip firmly, replace it without hesitation: a compromised screw can ruin an entire session.

Does the pack include any type of tool?

No. The pack contains only the 10 units of screws. The appropriate Allen key must be purchased separately.
