Mini 4WD Racing M2 x 10 Button Screw M4WD-21/RE by 3Racing  [M4WD-21/RE]

Technical note on M4WD-21/RE red M2 x 10 socket button screw

This red M2 x 10 socket button screw is presented as an aftermarket replacement for Mini 4WD maintenance and light tuning work. The description highlights fitment concerns, finish identification and practical handling advice relevant to racers and serious hobbyists.

Compatibility is with Mini 4WD components accepting standard M2 threaded fasteners. The red finish simplifies identification during rapid pit-side swaps; however, verify head clearance and thread engagement in tuning setups where spacers and brackets change the mounting geometry.

Install using the correct hex driver and controlled torque to prevent rounding the socket. For performance builds, ensure threaded inserts are solid and replace any fastener with damaged threads to maintain consistent clamping and repeatable setups.
