M4WD-20/BK black M2 x 8 socket button screw specified for Mini 4WD fitment

This M2 x 8 socket button screw is supplied as a direct-format spare for Tamiya Mini 4WD assemblies, intended for builders who require consistent thread form and head dimensions when servicing 1/32 scale chassis and body mounts.

Fitment notes concentrate on compatibility and handling rather than installation steps. The screw conforms to common M2 thread standards found across many Tamiya Mini 4WD parts; verify original component thread type and tapped depth when replacing hardware on Super-II, MA, MS, AR, FM-A and similar chassis. Confirm head clearance and use appropriate washers or backing hardware to reduce stress on thin plastic bosses.

Technical guidance for advanced users: avoid over-torqueing into low-wall plastic sections, confirm full thread engagement before final tightening, and select low-viscosity thread retention for vibration-critical assemblies. The black oxide finish is cosmetic and aids uniform appearance across visible mounting points.

How to check thread engagement reliably?

Measure the tapped depth and trial-fit the M2 x 8 screw to ensure several full turns of engagement without contacting the boss base or bottoming out.

What clearance to allow around the screw head?

Allow sufficient head clearance for the socket driver and any adjacent components; account for washers or spacers that may increase the effective head height.

Recommended thread retention approach?

For recurring vibration, choose a removable thread-locker in small doses or use nylon-insert nuts where access allows, balancing serviceability with retention.

How to prevent boss deformation when tightening?

Use a washer or backing plate to spread load over a larger area and tighten to a controlled torque appropriate for the plastic thickness.

Best practices for spare management in a workshop?

Keep M2 fasteners organised by length and finish, and label compartments with the model number M4WD-20/BK to avoid selection errors during reassembly.
