1 mm nylon spacers

Fine Adjustment with Thunderslot 1 mm Nylon Spacers

In the preparation of a slot car, the small details make the difference between erratic behaviour and precise, repeatable driving. The 1 mm nylon spacers from Thunderslot (reference TH-WAS001) are one of those discreet yet essential components that any experienced preparer always has on hand in their toolbox.

Function and Performance

The spacers — also called positioning washers — are used to adjust the lateral position of wheels and axles within the chassis, correct unwanted play, and fine-tune the rolling geometry. The thickness of 1 mm makes them a common reference for intermediate adjustments, complementing spacers of other sizes when seeking an exact setup.

Made from nylon, they offer a combination of lightweight and strength suitable for club competition use or careful preparation builds. Nylon does not damage the surfaces of the axles or supports, and maintains its dimensional properties with the usual heat generated during a running session.

Compatibility and Installation

This type of spacer is widely used in slot cars from various brands and scales, especially in configurations that use standard axles of common diameter in the segment. Before installation, it is advisable to verify that the inner diameter of the spacer matches that of your car's axle, a detail you should check in the specifications of your specific model.

Installation does not require special tools: simply remove the wheel, place the spacer in the desired position on the axle, and reassemble. It is recommended to check the resulting lateral play before permanently securing the assembly.

Common Mistakes

• Accumulating too many spacers to compensate for a bent axle: the spacer corrects position, not geometry. If the axle is damaged, the correct action is to replace it.
• Not verifying the inner diameter before installation, which can lead to excessive play or inability to insert.
• Mixing materials indiscriminately: in applications where electrical conduction or greater rigidity is required, a metal spacer may be preferable. Nylon is ideal when seeking lightweight and non-conductivity.

Frequently Asked Questions

What exactly is a nylon spacer used for in a slot car?

It is used to laterally position wheels and axles within the chassis, eliminate unwanted play, and adjust the rolling geometry with millimetric precision.

Is nylon a suitable material for competition use?

Yes. Nylon is lightweight, does not damage axle surfaces, and maintains its dimensions with the heat generated during normal running. It is a common choice in club preparations and recreational competition.

Which brands or chassis is this spacer compatible with?

Thunderslot spacers are for general use. Compatibility depends on the inner diameter of the spacer relative to your car's axle. Check your model's specifications before placing an order.

How many spacers are included in the TH-WAS001 pack?

The information provided by the manufacturer does not specify the exact number of units per pack. We recommend checking it directly on the product sheet or contacting our team.

Can I combine 1 mm spacers with other sizes?

Yes, it is a common practice. By combining spacers of different thicknesses, very precise intermediate adjustments can be achieved that would not be possible with a single size.

Thunderslot 1mm nylon washers (TH-WAS001) are a go-to component for fine-tuning axle positioning in slot cars. Lightweight and durable, these nylon spacers help eliminate lateral play and optimise rolling geometry for club racing or careful home builds. Compatible with standard axle setups across multiple brands and scales, they are a practical addition to any slot car preparation toolkit.
