Small in size, decisive in assembly: M2.5x4 Torx T6 extra-flat head screws
In the preparation of a slot car, every millimetre counts, and the screw head is no exception. These M2.5x4 steel screws feature an extra-flat head of just 0.9 mm in height, making them the right choice when the clearance between parts is minimal and a conventional screw would protrude enough to rub, interfere, or compromise the assembly.

Why extra-flat head and Torx T6?
The extra-flat profile minimises the height of the head above the mounting surface, something particularly valued in slot car chassis where tolerances are very tight. The Torx T6 drive offers a larger contact surface between the tool and the screw compared to a Phillips or an internal hex of the same size, resulting in less risk of damaging the head when tightening firmly or disassembling repeatedly during tuning sessions.
Typical applications in the hobby
This type of screw frequently appears in the assembly and preparation of slot cars, both in securing bodies and in mounting chassis parts that require the lowest possible profile. Having a stock in the workshop prevents interruptions during a preparation session due to a lack of units or having damaged some during disassembly.
Frequently asked questions
What screwdriver do I need for these screws?
You need a Torx T6 screwdriver or key. It is important to use the exact size to avoid damaging the star profile of the head, especially in small metric steel screws.
Are they made of stainless steel or carbon steel?
The product description indicates that they are made of steel, without specifying the exact type. If this information is relevant to your application, we recommend consulting us before placing your order.
What is the purpose of the extra-flat head compared to a standard flat head?
The 0.9 mm extra-flat head minimises the height that protrudes from the mounting plane, which is critical in areas of the chassis where another part passes very close or where the surface needs to be almost flush.
Can I use them on materials other than slot?
Yes. Although they are common in slot car preparation, their M2.5 metric and extra-flat profile make them useful in any model assembly, dioramas, or miniature mechanisms where this type of fastening is required.
