Allen Grub Screws M2.5x2.5: Millimetric Fixing for Serious Preparation

In the tuning of a slot car, every screw matters. The M2.5x2.5 allen grub screws from Sloting Plus (ref. SP152501) are designed for those who leave nothing to chance on the preparation bench: M2.5 metric thread, 2.5 mm length, and allen head for controlled and clean tightening, without marks or deformations.

Features

• Metric thread: M2.5
• Length: 2.5 mm
• Drive: allen (internal hex)
• Pack contents: 20 units
• Manufacturer: Sloting Plus
• Reference: SP152501

Function and Performance

Grub screws of this type are commonly used to secure chassis components, motor mounts, axle supports, and other elements where a secure fastening is required in tight spaces. The allen drive allows access with the appropriate key even in hard-to-reach areas, which is common in competition chassis where space is at a premium.

Having a pack of 20 units ensures that you always have spares on hand, especially useful when working on multiple cars at once or participating in workshop days at the club.

Assembly and Preparation

For assembly, we recommend using the correctly sized allen key for the internal hex of the M2.5 head, applying a moderate and even torque. If the assembly will be subjected to intense vibrations during the race, a small amount of low-strength thread locker can be applied to prevent loosening without compromising future disassembly.

Compatibility

As a standard M2.5 metric fastener, they are compatible with all components that accept this thread, regardless of the chassis or accessory manufacturer. Always consult the technical documentation of your chassis or mount to confirm the appropriate length before assembly.

Common Mistakes

• Confusing the length: M2.5x2.5 indicates M2.5 thread and 2.5 mm length. Ensure that the depth of the housing in your component is compatible with this measurement.
• Using the wrong key: forcing the allen head with an incorrectly sized key can damage the hex and make disassembly difficult.
• Omitting thread locker: in high vibration applications, the screw may loosen with use. A minimal point of low-strength thread locker prevents this issue without complicating maintenance.

Frequently Asked Questions

How many units are included in the pack?

The SP152501 pack includes 20 M2.5x2.5 allen grub screws.

What allen key should I use to tighten them?

You need the allen key that corresponds to the internal hex of the M2.5 head. Check the specifications of your allen key set to identify the exact size; it is usually a 1.5 mm key for this screw diameter.

Are they suitable for any slot chassis?

As they are standard M2.5 metric fasteners, they are compatible with any component that uses this thread. Always verify that the 2.5 mm length fits the housing of your specific part.

Can I reuse them after disassembling the assembly?

Yes, as long as the grub screw shows no damage to the thread or the allen head. If thread locker has been applied, clean them well before reusing to ensure proper tightening.
