Serpent 440159 Replacement M4 Nut for Mini Spyder SER440001 - Steel Fastener  [SER440159]

Durable M4 Fastener for Mini Spyder Servicing

The Serpent 440159 M4 metal nut provides a straightforward replacement option for the Mini Spyder RTR EP SER440001 platform. This small-scale metal nut performs the basic function of retaining threaded connections found on hubs, drive components, and linkage points where M4 hardware is specified.

Intended compatibility covers models that use M4 nuts in their hardware inventory; the part listing points to the Mini Spyder RTR EP SER440001 chassis as the intended application. Before swapping a nut, inspect the thread condition and mating surface to ensure proper fit and to avoid damaging RC-scale aluminium or plastic parts.

Fitting tips: engage the nut by hand to confirm correct threading, then finish with the suitable spanner until firm; for joints exposed to vibration, a dab of medium-strength threadlocker can help retain the fastener without risking over-torque damage.

Kept as a service spare, this metal M4 nut helps maintain reliability during routine checks and quick repairs at the track or workshop.
