Race-focused M2 x 10 black socket button screw for tuning and service

This M2 x 10 socket button screw is supplied as a service and tuning spare for competitive 1/32 Mini 4WD use. Its nominal spec is M2 thread, 10 mm length, recessed hex socket drive and a black button head suited to low-profile fitments. Use it where a secure hex drive and minimal protrusion are required in tight setup locations.

Confirm fitment with the target chassis insert or bracket and verify that 10 mm engagement is compatible with local clearance under the car. Fit with the correct hex driver and moderate torque to maintain consistent clamping without damaging the socket recess.

Keep these fasteners in the pit kit for on-track repairs, body refits and setup changes where appearance and low head height matter. They are a straightforward, reliable spare for frequent service cycles.

When should I carry spares like this in the pit kit?

Carry them whenever you expect quick repairs or body swaps. Small fasteners are easy to lose and having M4WD-21/BK on hand avoids delays between heat runs.

How do I check thread engagement for setup changes?

Measure the depth of the mating insert and compare with 10 mm screw length. Ensure enough thread is engaged to hold components under race loads without bottoming out.

Is head profile important for roll damper placement?

Yes. A button head keeps the profile low and reduces snagging on rollers or stabiliser components. Confirm the chosen head height clears neighbouring parts during full suspension movement.

What driver technique prevents stripping the socket?

Use the correct hex key size, apply steady pressure aligned with the screw axis and avoid using rounded or worn drivers that encourage slipping.
