Angle axle holder

The detail that makes the difference in your anglewinder setup

In a prepared slot car, every component matters. The NSR axle grub screw (reference NSR4848) is the part responsible for properly securing the axle in anglewinder configurations, where the motor operates at an angle to the rear axle. A poorly resolved fixation at this point can result in play, loss of transmitted power, or even failures during the race. With this original NSR grub screw, that becomes a non-issue.

Function and performance

The grub screw acts as a locking and securing element for the axle within its housing, preventing unwanted axial movement. In an anglewinder configuration, where the transmission geometry already introduces some complexity, having a solid and precise fixation is essential to maintain correct alignment between pinion and crown gear, thus ensuring efficient and lossless transmission.

Compatibility and installation

This grub screw is designed for use in NSR chassis and mounts prepared for anglewinder configuration. As an original spare part from the brand, it guarantees the exact fit with NSR components of the same family. Before installing it, ensure that the axle and housing are clean and free from dirt or lubricant residues that may interfere with the fixation.

Common mistakes

• Over-tightening: this can deform the axle or damage the housing. Adjust firmly but without exceeding.
• Not checking the tightness after initial runs: in the first sessions, it is advisable to check that the grub screw has not loosened.
• Confusing with grub screws from other configurations: ensure that it is the specific one for angle axle (anglewinder), as measurements and geometries may differ.

Ideal for…

Preparers and drivers who assemble or maintain NSR cars with anglewinder configuration, both in clubs and in competition. Also for those who simply need to replace this wear part or have lost it during disassembly.

Frequently asked questions

What exactly is a grub screw in the context of slot?

It is a headless screw —or with a very reduced head— that screws into a lateral housing to press against the axle and secure it in position. It prevents the axle from moving uncontrollably during the operation of the car.

Is it compatible with all anglewinder chassis on the market?

It is specifically designed for NSR systems. Compatibility with chassis from other brands will depend on the measurements of the housing. Check the specifications of your chassis before installing it on third-party components.

What tool is used for installation?

Typically with an Allen key of the size corresponding to the grub screw. NSR and Sloting Plus offer suitable preparation tool sets for this type of operation.

How often should it be checked?

It depends on the intensity of use. In competition cars, it is advisable to check the tightness at each maintenance session, especially if the car has suffered any impact or has run on circuits with high vibrations.

The NSR4848 axle grub screw for anglewinder configurations is a precision replacement part designed to secure the axle in angle-drive slot car setups. Essential for competitive and club slot car racing, this original NSR component ensures tight axle retention, preventing unwanted movement and maintaining correct pinion-to-crown alignment. A must-have spare for any NSR anglewinder build or maintenance kit.
