Long M2 x 40 socket button screw for Mini 4WD assembly

This M2 x 40 socket button screw is intended for 1/32 Mini 4WD builds that require extra thread length for chassis plates, body mounts or accessory brackets. The fastener uses a socket-drive button head and a nominal 40 mm shank length, supplied as a single spare for assemblies that accept M2 threaded fixings of that size.

Fit depends on the mating thread form and available clearance in the chassis or add-on parts. Check standoff heights and hole depth before swapping parts. Use the correct hex key for M2 socket heads and tighten by hand torque to avoid stripping or deforming plastic components.

Excellent service, two of the items I purchased were out of stock but was given fair options on refund, store credit or replacement. I opted for replacement as there was a different version available and one of the items did arrive bent and they sent out

Which Mini 4WD locations typically take an M2 x 40 socket button screw?

Use this length where original fixings are replaced due to added spacers, long standoffs or accessory mounts; common examples are extended chassis stacks and reinforced body mounts. Always confirm the hole depth first.

Will this fit standard Mini 4WD kits from popular makers?

It fits components that accept standard M2 threads. Compatibility with a specific kit depends on insert type, nut style and clearance, so measure before fitting.

What hex key should I use to avoid damage?

Use a hex key sized for M2 socket heads. Apply steady hand torque and avoid using oversized drivers that can round the socket.

Should I add washers or nuts when using this screw?

That depends on the assembly. Where no captive nut or threaded insert exists, fit an appropriate nut and consider a washer to spread load if space allows.
