Mini Spyder MT Half-Thread M3x19.5 Screws 4-Pack - Serpent 440181  [SER440181]

Service half-thread M3x19.5 for Mini Spyder MT

This item is a four piece set of half-thread M3 screws, 19.5 mm long, specified for the Serpent Mini Spyder MT. It serves as a replacement fastener for mounting chassis components and body fixtures where a partial threaded length is needed for clamping while the smooth shank aligns parts.

Compatibility is focused on the Mini Spyder MT lineup and associated SER440001 chassis components listed by Serpent. When replacing hardware, match the original thread engagement and leave washers or spacers in their original positions to maintain setup dimensions.

Fitting advice: start screws by hand to prevent cross-threading, tighten in small increments and avoid excessive torque to protect plastic or aluminium bosses. Consider a low-strength threadlocker if the model runs in high-vibration conditions and confirm driver fit before reuse.
