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

Replacement M4 Metal Nut for Mini Spyder

The Serpent 440159 Metal Nut M4 is an RC-scale replacement nut designed for use with the Mini Spyder RTR EP SER440001 platform. As a simple hardware spare, it serves the basic role of securing threaded connections on wheel hubs, drive shafts, and suspension linkages where an M4 nut is specified.

Compatibility is limited to models that list M4 nuts in their hardware set; the linked category for this part identifies Mini Spyder Monster truck RTR EP SER440001 as the intended chassis. When replacing a worn or damaged nut, confirm thread fit and mating surface before installation to avoid cross-threading on RC-scale components.

Installation notes: hand-start the nut on the thread to ensure correct engagement, then tighten with the appropriate hand tool until snug; for metal-to-metal joints consider a small amount of medium-strength threadlocker if the joint is vibration-prone, and avoid over-torquing to protect RC-scale aluminium or plastic mating parts.

As a service item, this M4 metal nut supports field repairs and routine maintenance, making it a straightforward spare to keep with your on-track toolkit for quick fixes and setup adjustments.
