Special ROUND washer for chassis and mounts

The washer that makes a difference in slot chassis and pod adjustment

In the world of competitive slot racing, the smallest details are what separate a well-tuned car from one that fails to respond. The special round washer SP150042 from Sloting Plus is a perfect example of this: specifically designed to work with the rocking screw and any screw that needs to be precisely adjusted in its housing.

Function and performance

These washers have been conceived for three very specific uses within the preparation of a slot chassis:

• Adjustment of the rocking screw: they allow for fine calibration of the chassis movement over the pod, which is fundamental to achieving optimal grip in each section of the track.
• Regulation of the motor pod: when correctly interposed, they help minimize or control the play of the pod, directly influencing the transmission and behaviour of the car.
• Retention washer function: they hold the screw in position to prevent it from getting lost or falling onto the track during assembly or maintenance in the pits.

Assembly and preparation

With a thickness of just 0.15 mm, they become a very fine adjustment tool. It is common to stack several units to achieve the exact space needed for the screw, which is why the bag includes 40 pieces: more than enough for several preparations or to always have spares in the pit case. The stainless steel ensures they do not deform under pressure and resist rusting, even under intensive use conditions.

Ideal for…

Preparers and club drivers who work their chassis with precision, enthusiasts who frequently assemble and disassemble, and anyone who wants to ensure that no screw ends up lost on the track during a session.

Frequently asked questions

What screws is this washer compatible with?

It is designed for M2 screws and up to 2.1 mm in diameter, which are the most common in competitive slot chassis and pods.

How many washers does the bag contain?

Each bag contains 40 units, allowing them to be used in various preparations or to combine several to achieve the exact thickness adjustment needed for each assembly.

Can multiple washers be stacked?

Yes. With only 0.15 mm thickness, it is common to use two or more together to achieve the desired adjustment space in the screw housing.

What material are they made of?

They are made of stainless steel, making them resistant to deformation and corrosion, even with continuous use in tuning and competition sessions.

Do they serve as retention washers?

Yes. One of their specific applications is to act as retention washers to hold the screw in position and prevent it from falling onto the track during assembly or maintenance.

Are they suitable for regulating the motor pod?

Yes. They can be interposed in the assembly of the motor pod to minimize or control its movement, which directly influences the behaviour of the transmission.
