SH motor mounting screws for 1270 brackets

The correct screw to ensure your NSR motor doesn't move a millimetre

When preparing a slot car with real demands, every component counts. The SH motor mounting screws for 1270 brackets from NSR (ref. NSR4856) are the piece that guarantees the motor is perfectly anchored to its mount, without play or vibrations that could compromise performance or misalign the drivetrain.

Function and performance

These screws are designed to secure the SH motor in the NSR 1270 brackets. Poor anchoring of the motor can lead to:

• Vibrations transmitted to the chassis that degrade grip.
• Misalignment between pinion and crown gear, resulting in premature wear.
• Loss of consistency in lap times, especially in fast corners.

With the original NSR screws properly tightened, the motor operates exactly where it should, transmitting all its power to the rear axle without energy loss.

Compatibility

These screws are specific to the NSR 1270 brackets with SH type motors. If you have doubts about whether they fit your chassis configuration, check the reference of your motor mount before placing your order.

Assembly and preparation

The assembly process is straightforward, but deserves attention:

1. Place the motor in the 1270 bracket ensuring it is well seated.
2. Insert the screws without forcing: they should go in smoothly before tightening.
3. Tighten evenly and progressively on both sides to avoid generating asymmetrical tensions.
4. Check the pinion-crown alignment before closing the chassis.

Common mistakes

Replacing these screws with others of similar size but different thread pitch can damage the mount or fail to provide the necessary hold. Always use the original NSR reference to avoid track issues at the least opportune moment.

Frequently asked questions

What mount are these screws exactly for?

They are designed for the NSR motor mounts with reference 1270, intended for SH type motors.

How many screws are included in the NSR4856 pack?

The information on units per pack is not specified in the available data. We recommend checking directly with our team before placing the order if you need a specific quantity.

Can I use these screws with other NSR mounts?

Their compatibility with other NSR mount references is not confirmed. To ensure the correct fit, use them only with the 1270 mounts for which they were designed.

Is it necessary to use any thread lock?

It is not mandatory, but in competition cars where vibrations are intense, some tuners apply a small amount of weak thread lock to prevent the screws from loosening with continued use.
