This M2 x 6 socket button screw is supplied in light blue by 3Racing as a spare fastening solution for Tamiya Mini 4WD hardware. It is intended for replacement of M2 fasteners in body mounts and accessory fixings where a matched finish is desired.
From a setup perspective the screw is useful for fine-detail assembly and visual tuning of body and accessory positions. No statement is made here about material treatments beyond the light blue finish; confirm thread engagement and head clearance when using in precision or load-critical assemblies.
