Guide fixing screws

The fixing that your guide needs to perform uncompromisingly

When tuning a slot car to the limit, every component matters, and the guide fixing screws are no exception. A guide that is not properly anchored introduces play, imprecision in steering, and loss of contact with the braids, which directly translates into worse performance and less consistent lap times.

NSR, an undisputed leader in the world of competitive slot racing, includes in its spare parts catalogue these specific screws for guide fixing under the reference NSR4857. An essential consumable for those who work rigorously in the workshop.

Function and performance

The guide fixing screws have a specific mission: to ensure that the guide is perfectly attached to the chassis, without unwanted movements that could affect the car's geometry on track. A correct assembly guarantees:

• Firm and stable contact of the guide with the rail.
• Efficient transmission of current through the braids.
• More precise and predictable steering response.
• Reduction of vibrations and premature wear in the front area of the chassis.

Compatibility and assembly

These screws are designed to integrate with NSR's proprietary guide systems. If you have doubts about the exact compatibility with your chassis model, consult the reference on the official NSR website or contact our team before placing your order.

The assembly is straightforward, but it is advisable not to overtighten: adjust firmly without forcing, especially if working with plastic or resin chassis, where excessive tightening can damage the thread of the housing.

Assembly and preparation

For a proper setup, we recommend:

1. Thoroughly clean the guide housing before inserting the screws.
2. Check that no remnants of previous screws or burrs remain in the chassis.
3. Use a screwdriver suitable for the type of head to avoid damaging the screw slot.
4. Once assembled, check that the guide does not exhibit lateral or vertical play outside of the specified limits.

Common mistakes

• Overtightening: this can damage the chassis or render the thread unusable, especially in lightweight materials.
• Reusing deformed screws: if the screw has suffered, replace it. The cost is minimal and the impact on performance is significant.
• Ignoring wear: periodically check these screws, especially if you practice long sessions or compete regularly.

Ideal for…

Enthusiasts who carefully prepare their slot cars, club competitors seeking reliability in every race, and workshops that want to always have the correct consumables on hand for professional preparation.

They are designed for NSR guide systems, but exact compatibility may vary depending on the chassis model. We recommend verifying it with the specific reference of your chassis in the official NSR catalogue.

How often should I check or replace these screws?

It depends on usage. In regular competition, it is advisable to inspect them every few sessions. If you detect play in the guide or the screw shows deformation in the head, replace it immediately.

Do I need any special tools to mount them?

A suitable precision screwdriver for the type of screw head is sufficient. No specialized tool is required, although working calmly and without forcing is always the best practice.
