3Racing M4WD-26 specification note for Tamiya Mini 4WD

The M4WD-26 is supplied as a dedicated replacement fastener compatible with Tamiya Mini 4WD assemblies where an M2 x 30 socket button head is specified. The critical dimension here is the 30 mm length and correct M2 thread engagement for secure clamping in standoffs and chassis fixtures.

In workshop practice, ensure correct hex bit fit and controlled torque to preserve head integrity and avoid overloading small diameter threads. Verify that head profile and overall length clear adjacent components and do not alter roller spacing or body seating.

No assumptions are made regarding alloy or surface treatment; technicians should select appropriate corrosion or wear protection if required by the application. Store replacements sorted by thread and length to maintain consistent assembly and setup during service or tuning.

Excellent service, two of the items I purchased were out of stock but was given fair options on refund, store credit or replacement. I opted for replacement as there was a different version available and one of the items did arrive bent and they sent out

How should I verify thread engagement?

Confirm that at least several full turns engage in the receiving thread without bottoming out. Full engagement avoids shear loading and provides reliable clamp force.

Recommended driver technique for repeatable torque?

Use a precision hex driver and apply steady, hand-controlled torque. For repeatable results in setups, consider a small torque driver calibrated for low values.

When is a removable threadlocker appropriate?

A low-strength, removable threadlocker is suitable where vibration causes loosening but future service is anticipated. Avoid permanent adhesives on service fasteners.

Storage and inventory tips for small fasteners?

Keep items in labelled compartments by thread, length and head type to ensure correct part selection during maintenance and to preserve original vehicle setup.
