DIN 912 M2x4 Allen screws (4pcs) + key

The screws that every preparer has on hand in the workshop drawer

There are parts that seem minor until you need them and don’t have them. The allen screws DIN 912 M2x4 are exactly that: small, precise, and essential when you are adjusting a chassis, securing a motor mount, installing a guide, or re-tightening any component that requires a metric 2 with an allen head. This pack includes 4 units along with the corresponding allen key, so you have everything you need to get to work without searching for extra tools.

Product features

• Standard: DIN 912, cylindrical head screw with internal hexagon (allen).
• Size: M2 x 4 mm.
• Contents: 4 screws + allen key included.
• Reference: CXM303.

Function and applications in the slot workshop

The M2x4 size is one of the most common in the assembly and preparation of slot cars at 1/32 and 1/24 scale. It is frequently used to secure motor mounts, hold guides, secure chassis parts, or adjust suspension elements in those models that allow it. Having a small stock of these screws prevents interruptions during a preparation session, especially in the workshop or in the pit during a club competition day.

The allen head provides a clean and controlled tightening, without damaging the screw head with repeated uses, which is appreciated when you have to disassemble and reassemble the same component multiple times during tuning.

The included key: a detail that matters

The pack includes the allen key of the corresponding size. It may seem like a minor addition, but when you are at a club race or in a night practice session, you don’t always have the complete set of keys on hand. Having the right tool along with the screws is a real practical advantage.

Ideal for…

• Preparers and competition drivers who need spare fastening parts on hand.
• Enthusiasts who assemble or modify chassis and components at home.
• Slot workshops that manage multiple cars and regularly consume this type of fasteners.
• Anyone who has lost an original screw and needs to replace it with a reliable standard size.

Aspects to consider

Always check the exact size required by your component before using these screws. The M2x4 has a 4 mm effective length; if you need greater thread depth, other lengths are available. When tightening in plastic or soft materials, apply the correct torque: the allen head facilitates control, but excess can damage the housing.

Frequently asked questions

Which cars or brands are these screws compatible with?

As they are a standard DIN 912 M2x4 size, they are compatible with any component — from any brand — that uses this thread and length. They are not tied to a specific manufacturer.

How many screws does the pack include?

The pack includes 4 allen screws DIN 912 M2x4 plus the corresponding allen key.

Is the key the correct size for these screws?

Yes, the key included in the pack is specifically sized for the internal hexagonal head of the M2 screws in this batch.

Can I use these screws in direct thread on plastic or do I need a nut?

It depends on the component. Some chassis and slot parts have threaded housings in metal or hard plastic designed for this. In other cases, a nut is used. Always consult the instructions or the design of the part you are going to assemble.

Are they made of steel or another material?

The DIN 912 standard typically involves steel, but the manufacturer has not specified the exact material of this batch in the available information. If this detail is critical for your application, please consult us before placing your order.
