Tamiya Mini 4WD Fastener M2 x 12 Socket Button - M4WD-22 by 3Racing  [M4WD-22]

M4WD-22 M2 x 12 Socket Button Screw for Mini 4WD

This M2 x 12 socket button screw is a straightforward replacement fastener intended for Tamiya Mini 4WD models. It is designed for general joining and routine maintenance rather than performance modification, and works where a socket button head and M2 thread are required.

Made in steel, the screw gives higher tensile strength compared with brass or aluminium alternatives, though it can need surface protection if stored in humid conditions. Builders will often use this screw with matching M2 nuts or pressed-in threaded inserts depending on the subassembly being serviced.

Installation tips for experienced hobbyists: choose the correct hex driver to avoid rounding the internal socket, check thread engagement against panel thickness, and confirm clearance for nearby rollers or body mounts. For frequent disassembly, use thin washers to protect plated surfaces and avoid using this part as a drivetrain tuning item since it is a standard fastener.
