Precision pink M2 x 8 socket button screw M4WD-20/PK for tuning

This M2 x 8 socket button screw in pink is supplied as a compact spare for 1/32 Mini 4WD assembly and fine-tuning tasks. It is intended for situations where a low-profile M2 socket button head is required, providing a visible, colour-matched attachment option for body mounts, bumpers and small accessories used in competitive setups.

Technical advice: check head-to-roll clearance when stacking rollers or using slim bodies, and measure thread engagement in thin plastic posts to prevent stripping. Use a precision hex driver with the appropriate tip to avoid rounding the internal hex drive. Consider the pink finish as an identification aid rather than a performance coating unless the vendor lists specific anodising or plating.

Material and surface finish are not specified by the source; verify any high-wear application or proprietary insert compatibility before installation. For tuning work, confirm exact usable thread length with a caliper and trial fit any aftermarket components.

What is the effective thread length for mounting calculations?

Nominal length is 8 mm, but account for head thickness and any chamfer; measure with a caliper to determine the usable engagement for precise tuner installations.

Should I expect the finish to withstand frequent swaps?

Finish durability is unspecified; for repeated disassembly use low-torque drivers and avoid abrasive contact to reduce cosmetic wear on the head.

Is the screw suitable for aftermarket brass inserts?

It is designed for standard M2 threads; verify thread pitch and insert depth for compatibility with aftermarket brass or proprietary inserts before final fitting.

Best practice for installing M2 socket button screws?

Use a precision hex driver, apply steady torque, and avoid over-tightening into thin plastic posts. For repeatable results, mark torque settings on micro drivers or use thread locker sparingly where appropriate.
