Technical note: M4WD-18/RE red M2 x 5 socket button screw

Precision replacement M2 x 5 socket button screw in red, supplied for Mini 4WD assembly and service tasks. The screw head profile and shaft length are selected to align with common 1/32 Mini 4WD mounting points, reducing the need for alterations during replacement.

For serious hobbyists and workshop use, consistent head geometry aids repeatable clamping and aesthetic uniformity on display or restored chassis. The coloured head also assists in assembly sequencing and identification of serviceable fastenings.

Installation requires an M2 hex socket driver and attention to thread engagement depth, especially in thermoplastic inserts. For repeated service cycles consider metal threaded inserts or controlled torque settings to preserve both screw finish and parent material.

What tolerances should I expect on the M2 thread?

Threads conform to nominal M2 size; verify engagement fit in the target insert and check for any burrs or damage before installation.

Recommended torque settings for plastic inserts?

Use minimal torque sufficient to seat the head without crushing the insert. Exact values depend on insert material, but start low and test engagement.

Is the coloured plating compatible with enclosures?

The plated finish is made for visual consistency; check chemical compatibility if exposed to solvents or adhesives during finishing.

When should I upgrade to metal inserts?

If you service the same mounting point frequently or fit load-bearing components, install a metal insert to protect plastic threads and extend service life.
