Technical note: M4WD-20/RE red M2 x 8 socket button screw

A purpose-fit M2 x 8 socket button screw supplied in red finish for 1/32 Mini 4WD chassis that accept M2 fasteners. This component is intended as an aftermarket replacement to restore proper fastening where original screws are missing or damaged.

Use a 2.0 mm hex driver for installation and ensure correct thread engagement depth in thin plastic parts to prevent stripping. The button-head geometry provides a low profile while allowing reliable clamping for body panels and accessories. Keep spares sorted by length and head style for efficient pit-side servicing.

What is the recommended installation torque?

Use light hand torque sufficient to seat the head without deforming the material beneath; avoid power tools on shallow threads to prevent cross-threading.

Which driver size ensures proper engagement?

A 2.0 mm hex driver matches the internal socket and preserves socket geometry when used carefully.

How to verify thread depth before final tightening?

Trial-fit the screw to feel resistance, then back off and re-seat with a hand driver while checking that several full turns of engagement remain.

When is a screw no longer serviceable?

Discard screws with deformed sockets, rounded edges or damaged threads to avoid unstable assemblies and potential part failure.

Any tuning considerations for display versus running setups?

For running setups prioritise correct thread engagement and replace screws after impact; for display use consistent colour-matching but still ensure secure fit.
