Technical note on M4WD-23 M2 x 15 socket button screw

The M4WD-23 is a steel M2 x 15 socket button-head fastener intended as a direct replacement for common Tamiya Mini 4WD mounting points. It reproduces the typical thread engagement length and head profile used to secure body posts and minor brackets where a recessed hex drive is preferred for low-profile assemblies.

Functionally aimed at racers and tuners who require a reliable, economical spare, the steel material offers predictable strength and wear characteristics under normal running loads. For setups exposed to moisture or salt, consider corrosion-resistant alternatives or regular maintenance checks to preserve fitment and torque behaviour.

  • Install with a matched M2 hex driver to maintain socket integrity and repeatable torque control.
  • Limit torque when fastening into plastic posts to avoid thread shear in soft inserts.
  • Keep spares sorted by thread and length to ensure correct replacement during setup changes.

How does M4WD-23 compare to stainless variants?

Plain steel provides cost-effective strength but less corrosion resistance than stainless. For humid or coastal environments stainless is preferable to avoid surface degradation.

Recommended installation practice?

Use a short hex driver for better torque feel, thread the screw by hand initially, then tighten progressively to seating torque to prevent stripping.

Is M4WD-23 suitable for competition use?

Yes as a standard replacement; ensure correct torque and inspect for wear between races. For critical load points consider upgrading to higher grade or plated hardware.

Any tip for reuse of removed screws?

Inspect the internal hex for rounding and the thread for deformation. Replace if drive engagement or thread form is compromised to maintain reliable clamping.
