M2x4 special Phillips screws for motors (x20)

M2x4 Phillips Screws: the small detail that cannot be missing in any slot workshop

In the preparation of a slot car, significant advancements sometimes depend on the smallest elements. These M2x4 mm steel screws with a Phillips head are specifically designed for motor mounting, a critical point in the assembly of any chassis where precision and reliability of the fastening make the difference between a car that runs well and one that does not.

Main features

• Material: steel
• Size: M2 x 4 mm
• Head: Phillips (compatible with standard Phillips screwdriver)
• Contents: bag with 20 units
• Reference: SP159940

Function and performance

The M2 metric is one of the most common in slot motor fasteners. Its small diameter allows for precise work in very tight spaces, such as motor mounts on the chassis or the base, without compromising the strength of the fastening. The 4 mm length is suitable for most direct fastening configurations without the screw protruding or interfering with other internal components.

The Phillips head facilitates work with precision screwdrivers, both manual and electric, which is highly valued when performing frequent disassemblies and reassemblies during tuning sessions or between race heats.

Assembly and preparation

For a correct and lasting fastening, we recommend cleaning the housing before assembly and applying, if necessary, a minimal amount of low-strength thread locker. This prevents motor vibrations from loosening the screw during the race without hindering subsequent disassembly. The bag format with 20 units provides sufficient stock for several assemblies or for sharing among club members.

Ideal for…

• Preparers and drivers who frequently adjust motors.
• Club workshops with a high volume of cars in preparation.
• Enthusiasts who want to always have spare fasteners without relying on a single screw.
• Any assembly using a motor of standard dimensions in 1/32 or 1/24 scale.

Aspects to consider

Always check the thread specifications and length required by your chassis or base before placing an order. The M2x4 mm is a widely used size, but some manufacturers use different metric fasteners or Allen head types. In case of doubt, review the assembly manual of the chassis or consult your reference preparer.

Frequently asked questions

What type of motors are these screws intended for?

They are intended for securing motors in slot car chassis, where the M2 metric and 4 mm length are common dimensions. However, we recommend verifying the specific specifications of your chassis before assembly.

Are they compatible with standard screwdrivers?

Yes. The Phillips head is compatible with precision screwdrivers of type PH00 or PH0, which are the most common for working with fine modelling and slot fasteners.

How many screws does the bag contain?

Each bag contains 20 units, allowing for several assemblies or providing spare units for the workshop or club team.

Can they be used with thread locker?

Yes, it is perfectly compatible. If the motor is subjected to intense vibrations, a drop of low-strength thread locker helps maintain the fastening without hindering subsequent disassembly.

Are they suitable for resin or polycarbonate chassis?

It depends on the chassis housing. In general, the M2x4 mm fits well with metal inserts or nuts integrated into chassis of various materials, but it is advisable to confirm the metric and depth of the housing in each case.

Keep your slot car builds solid and race-ready with these M2x4 mm Phillips steel screws, specifically designed for motor mounting in 1/32 and 1/24 scale slot cars. Each bag contains 20 units — ideal for club workshops, frequent tuners, and competitive builders who need reliable fasteners always at hand. Reference SP159940 available at Ministry of Hobby.
