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

M4 Metal Nut for Mini Spyder Repairs

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

Compatibility is aimed at models that list M4 nuts in their hardware set; the linked part references the Mini Spyder RTR EP SER440001 chassis. When fitting a replacement nut, verify thread engagement and the mating surface before tightening to avoid cross-threading on RC aluminium or plastic components.

Installation notes: hand-start the nut to ensure correct threading, then tighten with the correct hand tool until snug; for metal-on-metal joints consider a small amount of medium-strength threadlocker if the joint sees vibration, and avoid over-torquing to protect mating parts.

As a service item, this M4 metal nut supports quick field repairs and routine upkeep, making it a handy spare in your track-side toolkit.
