Precision M4WD-21/LB M2 x 10 socket button screw for component maintenance

The M4WD-21/LB light blue M2 x 10 socket button screw is specified as a direct replacement for Mini 4WD applications that accept M2 hardware. Use this part when matching head profile, thread engagement and overall length are critical to assembly integrity and tuning reliability.

Inspect thread fit, head clearance and engagement depth before installation to ensure secure seating without interference. The coloured head aids part identification during race prep and routine servicing.

  • Application: direct replacement fastening screw for Mini 4WD M2-threaded parts
  • Checkpoints: thread size verification, head clearance, engagement length
  • Note: confirm seller pack quantity and verify fitment against the receiving component

What tolerance should I expect for thread fit?

Expect standard M2 nominal thread fit. For precision assemblies, measure the tapped hole and verify clearance to ensure correct engagement and avoid loosening under vibration.

How do I confirm head clearance for roller setups?

Measure from the mounting surface to the nearest moving part and compare to the button head height plus any washer thickness to confirm no contact occurs.

Is the finish specified for corrosion resistance?

Finish is primarily decorative; do not rely on it as a corrosion protection spec. For exposed applications consider hardware with specified coatings.

Recommended driver and torque practices?

Use the correct M2 hex driver and apply controlled torque. Over-torquing small fasteners can strip threads or deform heads, affecting fit and retention.

Should I keep spares for race events?

Yes, retaining a selection of common fasteners including M2 x 10 variants helps rapid repairs trackside and keeps setups consistent between heats.
