The 0.90 mm M2 Hexagonal Bit That Makes a Difference in the Workshop
When working with scale slot cars, precision is not optional: it is the foundation of all good tuning. This 0.90 mm hexagonal bit for M2 screws from Sloting Plus (ref. SP141019) is designed to fit into the common precision bit holders and screwdrivers found in the preparation workshop, allowing for work on the smaller hexagonal head screws found in chassis, motor mounts, crown gears, and other slot car components.
Function and Performance
Working with M2 screws is a daily task in slot preparation. Adjusting a motor mount, securing a crown gear in its exact position, or tightening the guide anchor are operations that require a bit that fits cleanly, without play, and transmits the right torque without damaging the screw. This 0.90 mm hexagonal profile bit fits precisely into that thread, avoiding the dreaded slip that ends up stripping the screw head and turning a simple operation into a headache.
Compatibility and Assembly
The SP141019 bit is designed to be used with precision bit holders and handles compatible with standard bits of this type. Before using it, it is advisable to check that the bit holder you have accommodates the shank of this bit. Sloting Plus offers various handles and bit holders in its tool catalogue specifically designed for this type of fine work.
Assembly and Preparation: Usage Tips
- Gently insert the bit until it is fully seated in the bit holder, without forcing it.
- Apply only the necessary torque: M2 screws in plastic or aluminium components have little tolerance for excessive tightening.
- Periodically check the condition of the hexagon on the bit; with intensive use, it may round slightly and lose precision.
- Always work with good lighting and, if possible, with a magnifying glass or workshop microscope to position the bit accurately on the screw head.
Common Mistakes
The most common mistake is trying to use a bit of the wrong size — for example, one of 0.89 or 1.0 mm — on an M2 screw. The result is always the same: play, slip, and damaged screws. Using the correct reference, in this case the SP141019 of 0.90 mm, is the only way to ensure clean and repeatable work. Another frequent mistake is applying lateral force while turning: the bit must always work in a straight line with the screw axis.
Frequently Asked Questions
What screws is this bit suitable for?
It is designed for M2 hexagonal head screws with a 0.90 mm recess, the most common type found in 1/32 and 1/24 scale slot car components.
What bit holders or handles is it compatible with?
It is compatible with standard precision bit holders that accept this type of bit. Sloting Plus has specific handles in its tool range; it is advisable to confirm compatibility with the specific handle you use in your workshop.
Is it a single-use bit or durable?
If used correctly — without forcing or working at an angle — it has a long lifespan. If used intensively or on very tight screws, the hexagon may wear down over time, at which point it should be replaced.
Can I use it to loosen very tight screws?
Yes, but with caution. The M2 size is delicate, and both the screw and the bit can be damaged if too much force is applied. For screws with high torque, it is ideal to use a handle with a good grip and work with short, controlled movements.
Does Sloting Plus manufacture other sizes of hexagonal bits?
Yes, Sloting Plus has a wide range of preparation and tuning tools, including bits of various sizes to accommodate the different screws found in slot cars.
The Sloting Plus SP141019 is a 0.90 mm hexagonal screwdriver bit designed for M2 screws, an essential precision tool for slot car preparation and tuning. Perfect for working on motor mounts, axle assemblies, guide fittings and chassis components in 1/32 and 1/24 scale slot cars. A must-have for any serious slot car workshop, compatible with standard precision bit holders.
