1.5mm torque screwdriver

The right torque, neither more nor less

In the preparation of a slot car, the torque with which the screws are tightened makes the difference between a reliable assembly and a damaged or poorly seated component. The SP141003 1.5 mm hex tip torque screwdriver precisely addresses that issue: it allows the correct tightening force to be applied to M3 allen screws, without over-tightening or under-tightening.

Main features

• 1.5 mm hex tip, compatible with M3 allen screws.
• Torque mechanism that controls the tightening torque and prevents excess force.
• Bag contents: 1 torque screwdriver + 1 1.5 mm allen key.
• Reference: SP141003.

Function and performance

M3 allen screws are present in numerous key elements of the slot car: motor mounts, chassis, axle supports, and other fine adjustment points. Excessive tightening can deform threads, crack plastic parts, or alter the geometry of the assembly. The torque mechanism of this tool acts as a safety limit: when the set torque is reached, the tool gives way before transmitting more force.

The result is a uniform and reproducible assembly, especially useful when working in series on multiple cars or when preparing competition material where consistency is crucial.

Assembly and preparation

The 1.5 mm hex tip fits directly into the most common M3 allen screws in the slot hobby. The included allen key allows for the adjustment or replacement of the tip without the need for additional tools, streamlining work at the preparation bench.

We recommend keeping the tool free of lubricants and dirt residues in the tip area to ensure the proper functioning of the torque mechanism over time.

Ideal for…

• Slot car preparers seeking consistency in tightening.
• Club competitors working with multiple cars and needing repeatable results.
• Hobbyists wanting to protect delicate plastic or resin parts from over-tightening.
• Any modelling workshop where M3 allen screws are used.

Points to consider

This tool is specifically designed for M3 allen screws with a 1.5 mm hex head. Before using it with other sizes, check the compatibility of the tip to avoid damage to screws or the tool itself.

Frequently asked questions

What screws is this screwdriver designed for?

It is designed for M3 allen screws with a 1.5 mm hex socket, which are commonly found in motor mounts, chassis, and other slot car assemblies.

What advantage does a torque screwdriver have over a conventional one?

The torque screwdriver automatically limits the tightening torque, preventing damage to threads or plastic parts due to excess force. It is especially valuable when working on delicate components or when uniformity in multiple assemblies is desired.

What does the bag include?

The bag contains one unit of the torque screwdriver and one 1.5 mm allen key.

Is it compatible with other screw sizes?

Available information indicates compatibility with M3 allen screws with a 1.5 mm hex socket. For other sizes, please consult the specific tools for each size available in our catalogue.

Do I need any additional tools for its use?

No. The 1.5 mm allen key included in the bag is sufficient for handling and adjusting the tool.

The SP141003 dynamometric screwdriver with a 1.5 mm hex tip is a precision tool designed for M3 allen screws, widely used in slot car preparation and assembly. Its torque-limiting mechanism prevents overtightening on delicate plastic or resin parts, making it a reliable choice for club racers, slot car tuners, and hobbyists who demand consistent, repeatable results on every build.
