Special Aluminium Chassis Screw Kit

When every tenth of a gram matters: duralumin motor pod screws to fine-tune the chassis to the limit

In the technical preparation of a competitive slot car, the details that go unnoticed are often the ones that make the difference. Motor pod screws are one of those elements: small, seemingly insignificant, but with a real impact on chassis behaviour. The Special Aluminium Motor Pod Screw Kit SP114030 from Sloting Plus meets this exact need: to reduce unsprung weight without sacrificing the precise fastening of the motor pod.

Technical specifications

• Material: Duralumin
• Size: M2.1 x 6.5 mm in length
• Weight per unit: 0.08 g
• Contents: bag with 2 units
• Reference: SP114030

To put the figure into context: a brass screw of equivalent size weighs approximately 0.25 g. The difference per unit may seem anecdotal, but when multiplied by the number of motor pod anchoring points and added to the rest of the preparer's adjustments, it contributes to a real reduction in unsprung weight in the chassis, which translates into greater stability and more precise response in corners.

Function and performance

These screws serve a dual purpose: on one hand, they eliminate play between the screw and the motor pod housing, achieving a firmer and more precise fit; on the other, they reduce the unsprung weight of the assembly, improving the dynamic behaviour of the car on the track. Sloting Plus has developed them with the preparer in mind who has already optimised the other components and seeks to fine-tune the final details.

Compatibility

They are compatible with most chassis and motor pods available in the slot market. Their size M2.1 x 6.5 mm is a widely used standard in the preparation of competitive cars, making them suitable for work on chassis from various brands and configurations.

Assembly and preparation: what you need to consider

Duralumin offers notable strength for its weight, but it is inferior to that of brass or steel. For this reason, it is essential to follow the assembly process below:

1. Do not use these screws to cut threads directly in plastic. The material can bend or break easily if forced onto a virgin thread.
2. Always prepare the thread first with a tap or with a brass or steel screw of the same size (M2.1). Once the thread is cut, the aluminium screw will enter effortlessly and without risk.
3. Lightly lubricate the thread before placing the screw in plastic. A minimal touch of lubricant reduces friction and protects the screw.
4. Use a flat screwdriver of the correct size to avoid damaging the slot. A screwdriver that is too small concentrates force on one point and can ruin the screw head.

By following these steps, the SP114030 screws will last in perfect condition and perform their function with total reliability.

Common mistakes

The most common mistake with aluminium screws in slot preparation is using them to cut threads directly on plastic or resin without first preparing the thread. The result is almost always the same: the screw twists or breaks during the first tightening. Preparing the thread in advance is a step that should not be skipped, regardless of the urgency in the workbench.

Frequently asked questions

How many screws are included in the bag?

Each SP114030 bag includes 2 units.

How does this screw differ from a standard brass one?

The main difference is the weight: 0.08 g compared to approximately 0.25 g for an equivalent brass screw. Additionally, duralumin better eliminates play in the housing due to its manufacturing tolerances, although its mechanical strength is lower, which is why it requires a specific assembly process.

Are they compatible with my chassis?

The size M2.1 x 6.5 mm is a common standard in most chassis and motor pods on the slot market. If your motor pod uses screws of that size, these will be directly compatible.

Can I tighten these screws the same way as brass ones?

It is not advisable to apply the same torque. Being aluminium, they are more sensitive to over-tension. Tighten them firmly but without forcing, especially if the thread is in plastic.

Do I need any special tools to mount them?

No special tools are required, but it is important to use a flat screwdriver of the correct size to avoid damaging the slot in the head. A screwdriver that is too small or of poor quality can ruin the screw on the first tightening.

What type of competition are they designed for?

They are particularly interesting for preparations aimed at championships where the weight of the assembly and the precision of the motor pod mounting have a real impact on lap times. They are also suitable for any enthusiast looking to take their car preparation to the next level.

The Sloting Plus SP114030 duralumin screw kit for motor pod mounting is a precision preparation component for competitive slot car racing. Weighing just 0.08 g per unit, these M2.1 x 6.5 mm screws significantly reduce unsprung weight compared to standard brass screws, improving chassis dynamics and eliminating play in the motor pod housing. Compatible with most slot car chassis and motor pods on the market, they are an essential detail for serious club racers and advanced hobbyists looking to fine-tune every gram.
