M2 steel screw with 4mm washer (10 units)

M2 Steel Screws with 4mm Washer from T800: the Small Detail that Makes a Difference in Competition

Within the 1/32 spare parts category, motor mounting hardware is one of the most underestimated elements and has significant consequences when it fails. These M2 steel screws with an integrated 4mm washer (ref. T839007) from T800 are designed for those who know that every component counts.

Function and Performance

The integrated 4mm diameter washer serves a clear technical function: to distribute the tightening pressure over a larger surface area, preventing the screw from marking or deforming the motor mount and reducing the likelihood of loosening due to vibrations during the race. The manufacturing steel allows for the necessary torque to be applied without the risk of deformation at the head.

The result is a well-secured motor, with no residual movement, which directly translates into stable gear engagement between crown and pinion and a power transmission without parasitic losses.

Compatibility

The M2 format is a common standard in 1/32 competition slot car chassis and mounts. This screw is especially recommended for the RT4 pod from Scaleauto, where the precision of the motor fit is critical in both Anglewinder and Inline configurations. Always check your chassis specifications to confirm the appropriate length before use.

Assembly and Preparation

• Use a precision screwdriver suitable for the type of head to avoid damaging it.
• Apply the correct tightening: over-tightening can mark the pod or hinder future motor adjustments.
• Check the condition of the screws after intense running sessions, especially if you compete on technical tracks that generate more vibration.
• The pack of 10 units allows you to always have spare units on hand, which is advisable when working with multiple chassis at once.

Common Mistakes

One of the most common mistakes in assembly is using screws without washers or with insufficient diameter washers, which concentrates the pressure on a single point and causes micromovements of the motor that affect gear consistency. Another common error is not replacing worn screws: a screw that has been tightened and loosened multiple times progressively loses tension.

Frequently Asked Questions

How many screws are included in this pack?

The pack contains 10 screws of M2 steel with an integrated 4mm washer.

What scale are these screws designed for?

They are designed for slot cars in scale 1/32, although the M2 format can also be found in some chassis of other scales. Always check the specifications of your pod or mount.

Are they only compatible with the RT4 pod from Scaleauto?

They are especially recommended for the RT4 pod from Scaleauto, but the M2 format is standard in many motor mounts for 1/32 competition slot cars. Check your chassis documentation to confirm compatibility.

What advantage does the integrated washer have over a screw without a washer?

The washer distributes the tightening pressure over a larger surface area, reducing the risk of marking the mount, preventing loosening due to vibration, and providing a more stable seat for the motor.

How often should I check or change these screws?

It is recommended to check the tightening after each competition session and to replace them when they show signs of wear on the head or when they no longer reliably maintain the tightening tension.
