Mini 4WD Precision M2 x 25 Socket Button Screw M4WD-25 by 3Racing  [M4WD-25]

Precision M2 x 25 socket button screw M4WD-25 for Mini 4WD service and tuning

This M2 x 25 socket button screw is a direct replacement fastener aimed at competitive Mini 4WD users who prioritise neat fit and repeatable service. Focus areas include head profile clearance for low-mounted rollers, consistent thread engagement at common chassis bosses, and exact driver sizing to protect the socket recess. Treat this as fitment guidance; verify compatibility with your specific car before final installation.

Intended compatibility includes standard Mini 4WD mounting locations on chassis such as MA, MS, AR, FM-A and Super-II. Low-profile socket heads reduce interference under compact components, but always confirm final clearance after fitting. For workshop efficiency, store spares by thread and length in labelled compartments for rapid changeovers.

Use a correctly sized hex driver with a clean tip to minimise cam-out and preserve the socket profile. If torque feel is abnormal during tightening, stop and inspect thread engagement rather than forcing the screw. This is a service spare; ensure the thread form and effective length match the original fastener before use.
